AI findings to review:
AI assistance is enabled for this report. Each section marked "AI-Assisted" contains AI-generated engineering observations produced during schematic-phase design review. Findings are based solely on connectivity, component values, and net annotations present in the schematic data at the time of analysis. The AI has no access to PCB layout, routing, thermal data, BOM pricing or availability, assembly constraints, or any information outside the schematic. Findings are observations to investigate, not pass/fail judgments. The absence of a finding for a given device or net does not constitute a clearance. STANDARD MODE — this analysis was produced by the standard model tier.
Based on user-selected TP insertion settings, 16 test point(s) were added and a modified design is available for download. Review the modified schematic and resubmit to update this report.

1.1 Design Overview

AI-Assisted — The CM4S_CORE_V02 carrier is built around a Raspberry Pi Compute Module 4S (U2), which seats in a 200-pin SO-DIMM socket. The module carries a Broadcom BCM2711 quad-core processor running at 1.5 GHz, with 1, 2, 4 or 8 GB of RAM. The design spans eleven hierarchical sheets: CPU module, general I/O, relays, Ethernet, the LAN1 Ethernet controller, microSD, HDMI, USB and power.

The carrier fixes three module configuration options. The CM4S USB port is strapped as a USB host through R51 to GND. Boot runs normally from the SD card or eMMC, and Q1 can force USB boot instead. The on-module bootcode EEPROM is left writable. Per the Raspberry Pi CM4S datasheet (Datasheet), the module draws about 7 W typical under load and 1.5 W at idle.

Storage and Non-Volatile Memory

A push-push microSD socket (J5) with card-detect is wired to the module's 4-bit SD/eMMC interface. A 93LC66A Microwire serial EEPROM (U10), organised 512 × 8, holds the configuration data for the USB hub and Ethernet controller.

Ethernet and USB Hub

Wired networking comes from a LAN9512I (U9), which combines a USB 2.0 hub with an integrated 10/100 Ethernet MAC and PHY. The PHY connects to an RJ45 MagJack (J4) with integrated magnetics and green and yellow status LEDs. A 25 MHz crystal (Y1) with 18 pF load clocks the device, and its two downstream USB ports extend the module's USB capacity. The SMSC LAN9512 datasheet (Datasheet) rates the industrial version from -40 °C to +85 °C ambient. It also specifies 231 mA typical supply current at full 100BASE-TX and USB High-Speed traffic.

The controller has its own 3.3 V island. Load switch U8 sources 3V3_LAN1, and VDD33A_LAN1 is derived from that rail through ferrite FB2. The controller's internal regulator generates VDD18CORE_LAN1.

USB Type-C Power and Data

USB Type-C receptacle J9 is the power-delivery input. It is managed by a HUSB238 USB PD 3.0 sink controller (U19), which is strapped to request 5 V at 3.25 A from the attached source. The CM4S reaches the controller over I2C at address 0x08 for monitoring and advanced settings. Per the Hynetek HUSB238 datasheet (source: Tomachie), the controller provides 120 % over-voltage protection and over-temperature renegotiation to 5 V. It also supports BC1.2 and Apple Divider 3 legacy charger detection.

A second Type-C receptacle (J7) serves the USB_BOOT_VBUS domain, and a stacked dual USB-A receptacle (J8) provides host ports. An FSUSB42 two-port USB 2.0 switch (U16) routes the module's single high-speed USB port between two paths. Per its datasheet (Datasheet), the switch has 720 MHz bandwidth and 3.9 Ω typical on-resistance. Ports are powered through RT9742 0.5 A current-limited load switches. U11 sources 5V_OTG_1 and U12 sources 5V_OTG_2, with U13 and U14 switching further 5 V branches. The Richtek RT9742 datasheet (source: Tomachie) gives a 0.6 A to 0.8 A current limit, a fault flag and output auto-discharge.

Display and Expansion I/O

HDMI receptacle J6 carries the module's HDMI transmitter, together with DDC, CEC and hot-plug signals. RClamp0524P TVS arrays (D12, D13, D15) protect the TMDS lanes.

General-purpose I/O leaves through a 40-pin 2.54 mm header (J2) and a 3-pin header (J1). This I/O is level-shifted by three TXS0108E-Q1 open-drain-capable translators (U3–U5) and a TXB0108 push-pull translator (U6). A single Schmitt buffer (U7) and a 3.5 mm pitch pluggable terminal connector (J3) complete the I/O. An IM03GR monostable 5 V-coil, 2 A double-pole changeover signal relay (K1) provides isolated switching. User interface consists of pushbutton S1 and eight indicator LEDs.

Power Architecture

The main converter is an LMR14050 synchronous-control buck regulator (U20), which generates Net-(C52-Pad1) through inductor L1. Per the TI LMR14050 datasheet (Datasheet), it accepts 4 V to 40 V, delivers up to 5 A and regulates from a 0.75 V reference. The power section also includes a 7 A, 60 V Schottky diode (D22) and a 1 A, 1000 V rectifier (D4).

The distributed rails are +BATT, +5V, +3V3, the switched USB and LAN rails, and GND, with a separate Earth chassis net. The +5V rail serves 24 pins and +3V3 serves 29 pins.

Operating Temperature

The CM4S module sets the board's operating range at -20 °C to +85 °C non-condensing. The CM4S datasheet notes that the BCM2711 throttles its clock to hold its internal temperature at 85 °C. The surrounding silicon meets or exceeds this range: the LAN9512I, RT9742 and FSUSB42 are rated from -40 °C to +85 °C ambient, and the TXS0108E-Q1 from -40 °C to +125 °C.

2 Component Value Properties

Component values should be in the VALUE property, either as a direct value (e.g. 100nF) or as a formula reference (e.g. =Capacitance). The typed property (Resistance, Capacitance, Inductance, Impedance, etc.) holds the actual electrical value; VALUE should point to it or contain the same data.

Multi-pin parts on diode designators (D12, D13, D15): the part has more than 4 pins. A diode designator (IEEE 315 D, IEC 81346 CR, GOST 2.710 VD) names a two- or three-terminal device or a bridge; an integrated protection array or an IC takes a U designator. Use a U designator so the part is treated as the integrated device it is.
Value Property Check
TypeCheckCountComponentsStatus
CapacitorsVALUE holds both the capacitance and a voltage rating (e.g. "0.1uF 50V", "10uF 6.3V"). Tomachie has already separated the two and uses the capacitance as the value, so the analysis and the AI read a clean magnitude and are not misled by the embedded rating — the misinterpretation risk is low. This is a cleanliness note, not a parsing failure: to keep the schematic self-describing and safe for downstream BOM/ICT/AOI tools that read VALUE literally, move the voltage into a dedicated Voltage property.

2.1 Not a Part Number

The manufacturer part-number field of these parts holds text that is not a manufacturer part number - a description, a placeholder, or more than one part - so it cannot be used to order the part or to find its datasheet. Replace it with the manufacturer's part number.

2.2 Part Number vs Stated Values

Each passive states its electrical facts twice: in the properties the designer set, and encoded inside the MANUFACTURER part number. This check decodes the manufacturer part number and compares the two. A distributor catalogue number is a different thing and cannot be used here - an LCSC C-number or a Digi-Key -ND number identifies a stock item, it encodes no capacitance, voltage or tolerance, so there is nothing in it to check against. Where the two readings disagree both are shown and neither is assumed correct: if VALUE is wrong the analysis used the wrong number, and if the part number is wrong the BOM orders the wrong part. Only the designer knows which field is authoritative. Parts whose numbering scheme is not recognized are reported as not checked rather than passed.

1 of 113 fitted resistor/inductor/capacitor part(s) carry no ordering part number: R13. Without a part number the BOM cannot state what to buy, and none of the part-number cross-checks in this section can run for these parts. Add a manufacturer part number to each part in the library.

2.3 Instance Properties To Review

The items below are properties of the placed component instances, not of the library parts they use.

6 instances write a quantity with a decimal comma in a text property (e.g. "0,31A"). This is valid European notation and is read correctly by this analysis; it does not affect the score. It is listed because a design delivered to tools and markets that expect a decimal point avoids misreads by using one convention throughout.

2.4 Capacitor Derating Check

Derating profilecommercial
Maximum ambient40 °C
Checks performed34
Over-specified22
A capacitor is checked here when the comparison can be made without an operating-point calculation: it has two terminals, sits between a power rail and ground so the rail's resolved voltage is the voltage across it, and states a voltage rating - a Voltage property, or a rating decoded from the part number. Every other derating check - for capacitors and for every other part class - is applied by the AI analysis within its report sections.
Derating applied: 15% (capacitor_voltage_pct = 85)
Status key: ↓ = Over-specified ✓ = Adequately rated
Derating is how much is taken off a part's catalogue rating. What remains is the most of that rating the part may be worked at - a 16 V capacitor derated 15% has a maximum permitted value of 13.6 V - and the part is correctly sized when the voltage its position applies stays within it, taken at the worst case of the rail's stated range. This judges DC working voltage only; ripple and switching transients are not included in the compared value.
Review: 22 part(s) carry a voltage rating far higher than needed. A lower-cost part can be used, down to the voltage indicated.
6 derating check(s) on 6 part(s) sit on rails whose level the schematic does not state directly. The AI analysis resolves those levels from the circuit and the device datasheets, and evaluates these parts there.

3.3 Open-Collector Pull-up Audit

Examined 1 candidate pin(s) on 1 net(s). 1 to verify with destination IC.
Open-collector / open-drain outputs need an external pull-up resistor to a power rail to function. This audit lists pins where a pull-up appears to be missing or where the pin type may not match the schematic library.

Information: this net may be missing a pull-up. The destination IC (MCU/FPGA/other) may enable a configurable internal pull-up — verify its datasheet. If none, add an external pull-up to a power rail.Review

3.4 Diode Polarity / Orientation

Diode polarity and orientation are read from the schematic. IPC-7351B (surface mount) / IPC-7251 (through-hole) Zero Component Orientation (ZCO) requires pin 1, the cathode, on the left with the footprint at zero rotation. Tomachie calls out symbols that do not meet ZCO because the PCB layout may have an error, assembly may insert the part backwards, initial ATE test generation from a netlist of only pins 1 and 2 will fail, or a novice may wrongly indict a correct part — consistency is the least-expensive path for everyone who handles the PCB.

3.5 Checks Not Performed

Items this report did not check, with the reason. None of these is a finding against the design - an item that was not checked says nothing about it either way.

Note 3: The figure these checks need was not taken from the part's datasheet, so they were not performed. This is a limitation of the analysis, not a finding on the design.

Checks the AI review could not perform are listed at Review severity in each AI section's Findings table, each naming the input that was missing.

4.2.1 Rail Voltage Annotation

The preferred way to state a rail's voltage is to record it in the design itself, where it travels with the schematic, survives every re-run, and can be read by anyone who opens the design: add VOLTAGE_NOM, VOLTAGE_MIN and VOLTAGE_MAX properties to the rail's net class directive, and VOLTAGE_EXCURSION_MAX for a survivable level outside normal operation.
2 power input(s) into this board were identified and characterized as follows. These are the levels the analysis uses.

USB_BOOT_VBUS5.00 V nominal, 4.75-5.50 V operating

4.3 USB-PD Contract Override Hazard

1 USB Type-C port(s) carry a USB-PD sink controller whose I2C port is wired to a bus mastered by a device that runs firmware. The controller's configuration strap sets the contract at power-up, but a register write can request a higher contract, and nothing in hardware on the rail stops it.
The part number supplied, HUSB238, names the family and no ordering variant. Where the family offers a variant with the I2C request path factory-disabled, or one that cannot request above the strapped level, that variant would remove this hazard; from the part number supplied it cannot be known whether such a variant was planned, and the controller's I2C wiring to U2 says it was not.
The controller's datasheet on the request path: The I2C has the highest priority. If using I2C to select a source PDO, it over writes the internal RDO which is created by VSET, ISET pins and internal factory fuse option, and the HUSB238 requests the I2C selected source PDO once the I2C commands are written.

The Net-(D18-A2) rail is not protected from a USB-PD contract above the strap being enabled over I2C by firmware. Absent such a variant, an over-voltage element that disconnects the rail above the strapped level is the protection against an errant request, from AI-generated or any other software.Medium

4.6 AI-Assisted Analysis

This section is created by AI and should be reviewed for accuracy. There may be some incorrect analysis, especially if any errors are called out in the Design Summary or Component Value sections. STANDARD MODE — this analysis was produced by the standard model tier.

4.6.1 Power Tree Overview

AI-Assisted — The board runs from a single USB Type-C sink input, J9. Its VBUS, Net-(D18-A2), is stated as 4.75 to 5.50 V. It passes D18 (ESD9B5.0ST5G to GND), then the 5 A fast-acting fuse F1 (Eaton 3216FF5), then the P-channel pass FET Q7 (AONR21307), and reaches +5V through R45 (0 Ω).

Q7 is controlled by the HUSB238 PD sink controller U19. U19 is powered from the fused side through R37 (10 Ω). Its straps request 5 V at 3.25 A: R42 (0 Ω) ties VSET to GND and ISET is open. This matches the designer's notes 'Vset 5V' and 'Iset 3.25A' on sheet POWER.

+5V feeds the LMR14050 buck U20, the RT9742 switches U11 and U12 (5V_OTG_1 and 5V_OTG_2 on the stacked USB-A connector J8), and U14 through R29 (HDMI_5V on J6). It also feeds the VCCB pins of U3 to U6, the K1 relay coil, and J2 pins 2 and 4.

U20 makes 3.3 V on Net-(C52-Pad1); its feedback divider sets 3.300 V. R50 (0 Ω) carries this onto +3V3, where further 0 Ω links fan out. R59 feeds +BATT (the CM4S VBAT pins). R6 feeds the CM4S 3V3 pins, with C1 47 µF. R8 and R10 feed the two GPIO bank supplies, each with 10 µF. R27 feeds U13, which switches SD_PWR to the microSD socket J5.

+3V3 also supplies U16, the VCCA pins of U3 to U7, and U8. U8 switches +3V3 onto 3V3_LAN1 at 3.3 V for the LAN9512 U9 and EEPROM U10, and through FB2 onto VDD33A_LAN1. U9 generates VDD18CORE_LAN1 (1.8 V) internally.

The boot port J7 (USB_BOOT_VBUS) reaches only J1, R35 and the Q6 gate; it powers nothing. K1 switches RELAY1_COM/NC/NO to J3 only, and that path carries no board power.

There is one conversion stage. All 3.3 V current, including the module's main VBAT supply, comes from U20, so the zero-ohm links and the single input contract set the board's current limits.

4.6.2 USB-C Input, PD Sink and Pass Switch

AI-Assisted — U19 presents its internal 5.1 kΩ Rd on the J9 CC1 and CC2 pins (Hynetek HUSB238 datasheet p.5, source: Tomachie). It requests the lower of its strapped VSET/ISET values and the source's advertised PDO (p.9-10). A source whose 5 V PDO offers 3 A, or a legacy Type-C source, therefore limits the board to that current, not to 3.25 A.

Q7 sits with its source on the fused VBUS and its drain on +5V through R45 (Alpha & Omega AONR21307 datasheet). Its body diode therefore blocks VBUS until U19 GATE sinks the gate through R39 5.1 kΩ; R38 51 kΩ holds the gate at the source otherwise. The gate-source arm is the R38 side of the divider. At 4.75 V input with the 300 Ω typical GATE pull-down it sees 4.75 × 51/(51 + 5.1 + 0.3) = 4.30 V. Figure 5 (p.3) gives 15.9 mΩ at that drive at 25 °C and 21.5 mΩ at 125 °C. The worst-case gate-source voltage is 5.01 V, far inside the ±25 V rating.

F1 carries the 3.25 A contract inside its 5 A rating and opens within 1 s at 350% of rating, 17.5 A (Eaton 3216FF datasheet p.1, Datasheet). A PD source limits current near its contract, so F1 is there for a failed source or a hard short. Two placement points remain. D18 clamps VBUS on the connector side of F1. F1's 5 A rating is above the 2.0 A rating of R45, which is in series behind it.

U19's own over-voltage protection trips at 120% of the requested voltage (p.11). It catches a source that overshoots the contract, not a contract raised over I2C.

The ESD9B5.0 parts on J9 VBUS, USB_BOOT_VBUS and both J8 VBUS rails are operated above a datasheet rating. VRWM for this part is 5.0 V, below the 5.5 V maximum on those rails. However, 5.5 V is still below the breakdown, V_BR(min) 5.8 V (at 1 mA, 25 °C), so the part is not in breakdown. There is leakage at 5.5 V, and that leakage is not characterised by the datasheet, which guarantees 100 nA maximum only up to 5.0 V; it rises with temperature (onsemi ESD9B datasheet p.2, source: Tomachie; USB Type-C specification). The leakage is a shunt from rail to ground in the microamp region at worst, so this is a specification-margin note only.

4.6.3 LMR14050 3.3 V Buck (U20)

AI-Assisted — U20 is a non-synchronous buck (Texas Instruments LMR14050 datasheet). D22 is the catch diode (Diodes Incorporated PDS760Q datasheet, source: Tomachie) and L1 the inductor (Vishay IHLP-2525CZ-01 datasheet). With EN tied to +5V, U20 starts once +5V passes its 3.5 to 3.9 V UVLO and ramps over 5.5 ms.

R41 82 kΩ sets 306 kHz. At 5 V input the duty cycle is about 0.69 and the on-time 2.2 µs, against a 75 ns minimum. With L1 at 8.0 µH under 2.7 A (8.2 µH graph, p.4), the ripple current is 0.48 A at 5 V and 0.57 A at 5.5 V, so the peak inductor current is about 3.0 A.

Output capacitance on U20's own sheet is C52 to C55: 188 µF nominal of X6S ceramic, the datasheet's own four-by-47 µF example bank (p.19). The ceramic DC-bias loss is not applied to that figure. With internal compensation the ceramic bank is suitable, ESR ripple is negligible, and capacitive ripple is about 1.2 mV. The reference band of 0.735 to 0.765 V and 1% resistors hold the output between 3.19 and 3.42 V.

The input side is the thin part of the stage. It has 4.4 µF of X7R (C49, C50) and no 0.1 µF capacitor at VIN on sheet POWER, while the input current pulses at about 2.7 A.

Losses at 2.7 A are about 0.48 W in D22 at 5.5 V input and up to 0.50 W in L1's 68 mΩ maximum DCR. U20 conduction is 0.45 to 0.90 W, between the typical and maximum on-resistance. This is consistent with the 89.7% efficiency read at 2.7 A on the 'Efficiency vs. Load Current' curve for 3.3 V output at 5 V input (p.7). That curve is drawn at 1 MHz; at 306 kHz the switching loss is lower. U20 therefore draws 1.99 A from +5V at 5 V input and 2.09 A at 4.75 V.

L1's 7.5 A saturation rating is below U20's 9.7 A maximum current limit. The composite core degrades gradually (6.69 µH at 8.99 A on the graph), so the exposure is limited to overload and short circuit, not normal operation.

4.6.4 Zero-Ohm Distribution Links and Compute Module Supplies

AI-Assisted — Both supply rails reach their loads through 1206 zero-ohm links. These are rated 2.0 A continuous and 10 A maximum, with under 50 mΩ resistance (Yageo RC1206 datasheet p.6, source: Tomachie).

The CM4S module is supplied entirely at 3.3 V (Raspberry Pi CM4S datasheet). VBAT comes through R59, the 3V3 pins through R6, and the GPIO banks through R8 and R10. VBAT at 3.3 V is inside the 2.5 to 5.25 V VBAT range (p.12).

The datasheet's typical figures are PVBAT 7 W and P3.3V 1 W (p.13); it notes these depend heavily on the application. On those figures the module draws 2.12 A on VBAT and 0.30 A on 3V3. With U9, the +3V3 total is 2.70 A, and all of it passes R50. R50 and R59 therefore carry more than their 2.0 A rated current. R45 is at its rating on the known +5V load alone, before any USB-A port current. R6 is lightly loaded.

U20 senses its output ahead of R50, so the link's drop is outside the regulation loop: up to 0.135 V at 2.7 A. At the low tolerance corner this leaves +3V3 at 3.05 V and 3V3_LAN1 at 3.03 V. That still meets the LAN9512 3.0 V minimum, but with almost no margin. A link with a higher current rating and lower resistance resolves both the rating and the drop.

+BATT has no capacitor of its own. The module's VBAT load steps are served through R59, from C1 (behind R6) and from C52 to C55 (behind R50).

The GPIO banks run at 3.19 to 3.42 V, less the R50 drop. This is inside the 1.71 to 3.45 V operating range and below the 3.6 V absolute maximum.

The board loads on the module's GPIO pins are CMOS inputs plus two I2C pull-ups that the pins sink. This leaves the 50 mA per-bank allowance (p.6) almost entirely for the off-board loads reached through the level translators.

4.6.5 RT9742 Load Switches

AI-Assisted — Five RT9742 switches gate the secondary rails (Richtek RT9742 datasheet, source: Tomachie). Each is rated 0.5 A, with a 0.6 to 0.8 A current limit and 70 mΩ typical on-resistance.

U8 is enabled by U2 GPIO29 on LAN1_EN. It passes +3V3 to 3V3_LAN1 for U9 and U10, and through FB2 to VDD33A_LAN1. Its 0.28 A load is well inside the rating; at 3.3 V input the 84 mΩ on-resistance read from the graph costs 23 mV.

U11 and U12 are enabled by U9 PRTCTL2 and PRTCTL3. They pass +5V to the two J8 USB-A VBUS pins. Those pins carry only the ESD9B5.0 clamps and the D7/D8 indicator branches, with no capacitance at all. The datasheet requires at least 120 µF per downstream-facing port. Without it, a hot-plugged device charges from the switch alone and the port voltage dips at every load step. The F̅L̅G̅ outputs of both switches are left unconnected, so U9 receives no port over-current report.

U13 passes +3V3 (via R27) to SD_PWR for J5, with C41 10 µF and D11 on the output (Nexperia PTVSXS1UR datasheet). Its EN sits on SD_VDD, which R28 pulls to 3.3 V, so SD_PWR follows +3V3.

The same SD_VDD net is the CM4S SDX_VDD bank supply (U2_4, U2_6). The CM4S datasheet specifies this pin as the SDIO voltage, 1.71 to 3.45 V (p.12), and R28 10 kΩ is its only feed. The SD pad bank is therefore unpowered while the card is powered. The card then back-drives the pads through the SDX_CLK, SDX_CMD and SDX_D0 to SDX_D3 lines.

U14 has EN tied to its own VIN behind R29 and supplies HDMI_5V with C43 100 nF.

The five switches have 0.1 to 1 µF on their inputs. The datasheet shows 10 µF on VIN in every application circuit.

4.6.6 LAN9512 Supply Domain

AI-Assisted — U9 draws 231 mA typical across VDD33IO and VDD33A at 100BASE-TX full duplex with maximum USB traffic (SMSC LAN9512 datasheet p.237, Datasheet). The magnetics draw about 42 mA more at 100BASE-TX and about 104 mA at 10BASE-T.

FB2 filters VDD33A_LAN1 from 3V3_LAN1, and each VDD33A and VDD33IO pin has its own 100 nF. U9's internal regulator produces VDD18CORE_LAN1 and VDD18USBPLL. VDD18USBPLL feeds VDD18ETHPLL through FB1, as Figure 2.2 (p.27) draws. Both beads are the specified 120 Ω at 100 MHz, 2 A type (Murata BLM18PG datasheet p.1).

The 1.8 V pins use 10 nF where Figure 2.2 shows 0.1 µF. VDD18ETHPLL carries 1 µF plus 10 nF instead of the figure's 0.1 µF. The figure is a reference circuit, so these are notes, not defects.

The magnetics centre taps J4_4 and J4_5 are fed from VDD33A_LAN1 through R20 10 Ω, with C39 22 nF to ground. The share of the centre-tap current that passes R20 is not set by anything on the schematic. Its bound, the full 104 mA 10BASE-T figure, would put 1.04 V and 0.11 W across an 0603 whose power rating is not stated.

The three LED branches (R21 to R23, 330 Ω to VDD33A_LAN1) add about 12 mA, which U9 sinks.

4.6.7 Power-Up Sequence

AI-Assisted — J9 VBUS rises. U19 powers from the fused side through R37 (UVLO 3.1 V rising) and presents Rd on CC1 and CC2.
U19 turns Q7 on through R39 and +5V rises. In the default ordering variants this happens after power-on reset; in variant 006DD it happens after the contract (p.15). The part number HUSB238 does not select a variant.
With +5V present, U14 enables HDMI_5V (EN tied to VIN, 2.1 ms turn-on), and the U3 to U6 VCCB pins and U11/U12 inputs are live. U20 passes UVLO and ramps Net-(C52-Pad1) over 5.5 ms.
+3V3 rises through R50 to the CM4S VBAT, 3V3 and GPIO bank supplies, U16, the U3 to U7 VCCA pins, U8 VIN, and U13 through R27. R28 enables U13 immediately and SD_PWR follows.
The CM4S boots and drives GPIO29 (LAN1_EN) high. U8 turns on 3V3_LAN1 and VDD33A_LAN1, and U9 brings up its 1.8 V supplies.
U9 drives PRTCTL2 and PRTCTL3, enabling U11 and U12 and the J8 port VBUS.
At power-down, U20 keeps regulating until +5V falls to about its UVLO, then +3V3 falls with it. The translators therefore keep VCCA at or below VCCB in both directions.

4.7 Observations

AI-Assisted — The U19 I2C pins (U19_6 SDA, U19_7 SCL) reach CM4S GPIO0 and GPIO1 directly through R52 and R53 (0 Ω). R43 and R44 (3.3 kΩ) pull them up to +3V3, so U2, which runs firmware, masters the bus.

The schematic establishes three things: the 5 V strap, that live bus, and a path from VBUS through F1, Q7 and R45 to +5V with nothing that limits voltage. The datasheet establishes the override: 'The I2C has the highest priority. If using I2C to select a source PDO, it over writes the internal RDO which is created by VSET, ISET pins and internal factory fuse option, and the HUSB238 requests the I2C selected source PDO once the I2C commands are written' (p.10). The part number HUSB238 names the family and no ordering variant. The highest requestable level is 20 V (the VSET open row and the 20 V default SNK_PDO2, p.9).

At a sustained 20 V, the elements on the path behave as follows:
- D18 conducts far beyond its rating and fails.
- F1 sees normal current and stays closed.
- Q7 (30 V) conducts.
- U19's over-voltage threshold moves up to 24 V with the request.
- U20 (44 V absolute maximum) survives and shields the CM4S, U9 and the 3.3 V logic.
- C49/C50 and C7 to C9/C12 withstand 20 V.
- U11, U12 and U14 (7 V absolute maximum), U3 to U6 (6.5 V on VCCB) and C37/C38 (10 V) do not.

The cheapest fix is at the Q7 gate node. R38 51 kΩ pulls the gate to the source, and U19 sinks it through R39 5.1 kΩ. An over-voltage comparator or protection controller that pulls the gate to the source therefore overrides U19. Q7 then conducts only when U19 asserts GATE and VBUS is in band. The trip threshold belongs between the 5.5 V band ceiling and the 6.5 V lowest downstream absolute maximum. The sensing input must withstand 25 V, the HUSB238 supply maximum. The single-part alternative is an OVP load switch with an enable input in place of Q7, driven by U19 GATE.

Of the other findings, the SDX_VDD feed is the one that stops a function outright. The jumper current ratings, the bare USB-A VBUS pins and the D18/F1 order should be settled before layout.

4.8 Findings

AI-Assisted —
#DeviceRailObservationSeverity
4.8.1U2 (CM4S), R28SD_VDDNo power source feeds U2_6 SDX_VDD. Its only feed is R28 10 kΩ from Net-(U13-VIN) at 3.3 V, at most 0.33 mA; R28 also holds U13 EN on but is not a supply for the SDIO bank (SDX_VDD operating 1.71-3.45 V, Raspberry Pi CM4S datasheet p.12). Second hazard: with SD_PWR powered by U13, the card on J5 back-drives the unpowered pad bank through SDX_CLK, SDX_CMD and SDX_D0-SDX_D3. Fix: feed SD_VDD from +3V3 through a 0 Ω link with local decoupling, as R8/C2 do for GPIO0-27_VDD; U13 EN stays on.High
4.8.2U19 (HUSB238), Q7 (AONR21307)+5VProtection is needed at the Q7 gate: a 20 V request over I2C from U2 reaches U11, U12 and U14 (RT9742, VIN absolute maximum 7 V) and U3 to U6 (VCCB absolute maximum 6.5 V) on +5V. Fix: add an over-voltage sense that pulls the Q7 gate to its source above about 6 V, with its input rated for at least 25 V, or replace Q7 with an OVP load switch whose enable is driven by U19 GATE.Medium
4.8.3R50, R59 (RC1206FR-070R)+3V3, +BATTR50 carries the whole 3.3 V load, 2.70 A, and R59 the CM4S VBAT current, 2.12 A (PVBAT 7 W, CM4S datasheet p.13). Both exceed the 2.0 A jumper rated current (Yageo RC1206 datasheet p.6, source: Tomachie). Fix: replace both with links rated at least 3 A continuous; this also reduces the up-to-0.135 V drop R50 adds outside U20's loop.Medium
4.8.4R45 (RC1206FR-070R)+5VR45 carries the whole +5V load. The known load is 2.02 A (U20 input 1.99 A at 2.7 A output and 89.7% efficiency, K1 coil 28 mA, LEDs), at the 2.0 A jumper rated current (Yageo RC1206 datasheet p.6, source: Tomachie), before the J8 USB-A ports (U11/U12 rated 0.5 A each), HDMI_5V and J2 pins 2 and 4 are added. Fix: replace R45 with a link rated at least 5 A continuous, which also coordinates with F1.Medium
4.8.5U11, U12 (RT9742), J85V_OTG_1, 5V_OTG_2Neither USB-A VBUS has any capacitor. The datasheet states each downstream-facing port requires at least 120 µF between VOUT and GND, plus a 0.1 µF local bypass (Richtek RT9742 datasheet p.13, p.7, source: Tomachie). Fix: add at least 120 µF low-ESR plus 0.1 µF ceramic at J8 pins 1 and 5.Medium
4.8.6F1 (3216FF5), R45+5VProtection gap: F1 is rated 5 A (Eaton 3216FF datasheet p.1), above the 2.0 A rated current of R45, which carries the whole +5V load in series behind it, so F1 does not protect R45. Fix: fitting R45 with a link rated at least 5 A, which the load needs anyway, restores coordination.Low
4.8.7D18 (ESD9B5.0ST5G), F1Net-(D18-A2)D18 sits between the J9 VBUS pins and F1, on the unfused side, so F1 cannot interrupt a failed-short D18 or a sustained over-voltage into it. Fix: move F1 to the connector side of D18 so the clamp is downstream of the fuse.Low
4.8.8L1 (IHLP2525CZER8R2M01), U20Net-(D22-K)The 7.5 A typical saturation current is below the 9.7 A maximum high-side current limit of U20 (TI LMR14050 datasheet p.5), so an overload or short drives L1 past saturation before U20 limits. The 8.2 µH graph (Vishay IHLP-2525CZ-01 datasheet p.4) shows 6.69 µH at its last point, 8.99 A. Fix: an 8.2 µH part with saturation current above 9.7 A (the datasheet design example uses 10 A, p.18).Low
4.8.9D18, D25, D30, D31 (ESD9B5.0ST5G)Net-(D18-A2), USB_BOOT_VBUS, 5V_OTG_1, 5V_OTG_2Operated above a datasheet rating: VRWM 5.0 V is below the 5.5 V maximum on these rails. 5.5 V is below V_BR(min) 5.8 V (1 mA, 25 °C), so the parts are not in breakdown, but leakage above 5.0 V is not characterised (100 nA maximum guaranteed only to 5.0 V). The leakage is a shunt in the microamp region at worst. A 6 V standoff class part restores the guarantee at a modestly higher clamp level (onsemi ESD9B datasheet p.2, source: Tomachie; USB Type-C specification).Review
4.8.10U20 (LMR14050)Net-(C52-Pad1)U20 permits 4 A, derated 20% (regulator_output_current_pct = 80) from its 5 A rating (TI LMR14050 datasheet p.1). The known 3.3 V load is 2.70 A (CM4S VBAT 2.12 A and 3V3 0.30 A from PVBAT 7 W and P3.3V 1 W, U9 0.27 A), not including the SD card on SD_PWR and J2 pins 1 and 17. Check that the total stays below 4 A.Review
4.8.11L1 (IHLP2525CZER8R2M01)Net-(C52-Pad1)L1 permits 2.8 A, derated 30% (inductor_current_pct = 70) from its 4 A heating rating. The known load current is 2.70 A, not including the SD card and J2 3.3 V pins. Check that the total stays below 2.8 A. The 8.2 µH graph (Vishay IHLP-2525CZ-01 datasheet p.4) gives 8.0 µH and a 9.9 °C rise at 2.7 A, so the hot spot is about 50 °C at 40 °C ambient against the 125 °C maximum.Review
4.8.12U20 (LMR14050)Net-(C52-Pad1)Switch conduction at 2.7 A is 0.45 W with the 90 mΩ typical and 0.90 W with the 180 mΩ maximum on-resistance. At 43.2 °C/W from 40 °C ambient this gives a 59-79 °C junction, against an 85 °C limit (125 °C less 40 °C). The on-resistance is stated at VIN 12 V (TI LMR14050 datasheet p.5); U20 runs at 5 V input here. The 5 V on-resistance value was not available at report generation time.Review
4.8.13U20, C49, C50+5VInput bypass is C49 and C50, 2.2 µF 50 V X7R each (4.4 µF). This matches the datasheet's 5 V design example but is below the 4.7-10 µF typical recommendation, and no 0.1 µF high-frequency capacitor is drawn at U20 VIN on sheet POWER (TI LMR14050 datasheet p.20).Review
4.8.14U8, U11, U12, U13, U14 (RT9742)+3V3, +5V, Net-(U13-VIN), Net-(U14-EN)Input bypass is C20 1 µF (U8), C37 and C38 1 µF (U11, U12), C46 100 nF (U13) and C42 100 nF (U14). The datasheet shows 10 µF on VIN in every application circuit and strongly recommends it (Richtek RT9742 datasheet p.7, p.13, source: Tomachie).Review
4.8.15U11, U12 (RT9742), U95V_OTG_1, 5V_OTG_2F̅L̅G̅ (U11_3, U12_3) is unconnected. A J8 port over-current is limited and timed out by the switch but not reported to U9 PRTCTL2/PRTCTL3, which take the switch's over-current signal on the same pin (SMSC LAN9512 datasheet p.28-30). Wiring F̅L̅G̅ to PRTCTL2/PRTCTL3 with a pull-up gives the hub its over-current report.Review
4.8.16U2 (CM4S)+BATTThe four VBAT pins carry about 2.1 A with no capacitor on +BATT; the nearest bulk is C1 47 µF behind R6 and C52-C55 behind R50. A 22-47 µF ceramic at the VBAT pins keeps the module's load steps off the R50/R59 links.Review
4.8.17U19 (HUSB238)+5VThe known +5V load is 2.02 A (U20 input 1.99 A, K1 28 mA, LEDs), not including the J8 USB-A ports, HDMI_5V and J2 pins 2 and 4. Check that the total stays below the 3.25 A contract strapped on ISET.Review
4.8.18U2 (CM4S)Net-(C2-Pad1), Net-(C3-Pad1)Each GPIO bank allows 50 mA total (Raspberry Pi CM4S datasheet p.6). The on-board loads on the module's GPIOs are CMOS inputs (U8 EN, U16 SEL, level-shifter A ports) plus the R43/R44 3.3 kΩ I2C pull-ups, which the pins sink (1 mA each, not sourced from the bank). The loads reached through U3-U6 to J2 are off-board and unknown, and have about 50 mA per bank available.Review
4.8.19U9 (LAN9512)VDD18CORE_LAN1, Net-(U9A-VDD18ETHPLL), Net-(U9A-VDD18USBPLL)Figure 2.2 (SMSC LAN9512 datasheet p.27) shows 4.7 µF + 0.1 µF + 0.1 µF on VDD18CORE and 0.1 µF on VDD18ETHPLL. Fitted are C18 4.7 µF with C23 and C26 10 nF, and C21 1 µF with C15 10 nF. VDD18USBPLL has C24 1 µF as shown, plus C27 10 nF. The figure is a reference circuit, not a stated minimum.Review
4.8.20R20 (10 Ω)Net-(C39-Pad1)The magnetics centre taps (J4_4, J4_5) are fed from VDD33A_LAN1 through R20 10 Ω with C39 22 nF. The datasheet gives about 42 mA (100BASE-TX) to 104 mA (10BASE-T) magnetics consumption (SMSC LAN9512 datasheet p.237); the bound of the full 104 mA through R20 is 1.04 V and 0.11 W. Check that the centre-tap current through R20 stays within its power rating.Review
4.8.21K1 (IM03GR)RELAY1_COMK1 switches RELAY1_COM/NC/NO to J3 only, and powers nothing on the board. The switched voltage at RELAY1_COM and the most the off-board load draws are not stated; state both so the K1 contact ratings can be judged.Review
4.8.22C49, C50 (CL31B225KBHNNNE)+5VA 50 V part with 5.5 V applied. Derated 15% (capacitor_voltage_pct = 85) it permits 42.5 V, far beyond the position; a 16 V X7R would serve, at the cost of more DC-bias loss (Samsung CL31B225KBHNNNE datasheet p.1).Review
4.8.23C23, C26 (CC0603KRX7R9BB103)VDD18CORE_LAN1A 50 V part with 1.8 V applied. Derated 15% (capacitor_voltage_pct = 85) it permits 42.5 V; a 16 V part would serve (Yageo CC0603 X7R datasheet p.5).Review
4.8.24C7, C8, C9, C12, C42 (CC0603KRX7R8BB104)+5V, Net-(U14-EN)A 25 V part with 5.5 V applied. Derated 15% (capacitor_voltage_pct = 85) it permits 21.25 V; a 16 V part would serve.Review
4.8.25C4, C5, C6, C10, C11, C29-C34, C36, C46 (CC0603KRX7R8BB104)+3V3, VDD33A_LAN1, Net-(U13-VIN)A 25 V part with 3.3 V applied. Derated 15% (capacitor_voltage_pct = 85) it permits 21.25 V; a 16 V part would serve.Review
4.8.26U19 (HUSB238)Net-(D18-A2)VSET is tied to GND through R42 (0 Ω), the 0 kΩ row (5 V); ISET is open, the 'Open = 3.25 A' row. Both decode to table rows and match the designer's notes 'Vset 5V' and 'Iset 3.25A' on sheet POWER (Hynetek HUSB238 datasheet p.9-10, source: Tomachie).✓
4.8.27U19 (HUSB238)Net-(U19-VIN)VIN is fed from the fused VBUS through R37 10 Ω, with C47 1 µF 50 V X7R to GND, as the datasheet requires (1 µF ceramic close to VIN, 10 Ω series in the application circuit; Hynetek HUSB238 datasheet p.1, p.9, source: Tomachie). The 3.1 mA supply current gives a 31 mV drop.✓
4.8.28U19 (HUSB238), Q7Net-(U19-GATE)The open-drain GATE output reaches the Q7 gate through R39 5.1 kΩ, with R38 51 kΩ from gate to Net-(Q7-S1) as its pull-up, matching the 49.9 kΩ / 5.1 kΩ application circuit (Hynetek HUSB238 datasheet p.12, source: Tomachie). Sink current at 5.5 V is 1.07 mA against the 10 mA GATE maximum (p.5).✓
4.8.29Q7 (AONR21307)+5VWorst-case VGS is 5.5 V × 51.51/(51.51 + 5.049) = 5.01 V (R38 +1%, R39 −1%, GATE at 0 Ω), against ±25 V derated 25% (mosfet_vgs_pct = 75) to 18.75 V. VDS is 5.5 V against 22.5 V (mosfet_vds_pct = 75). At 4.75 V input the gate sees 4.30 V, and Figure 5 gives 15.9 mΩ at 25 °C and 21.5 mΩ at 125 °C, so 3.25 A dissipates at most 0.23 W (12.5 °C rise at 55 °C/W). 3.25 A is well inside 17 A derated 30% (mosfet_id_pct = 70) (Alpha & Omega AONR21307 datasheet p.1-3).✓
4.8.30F1 (3216FF5)Net-(D18-A2)A 5 A fast-acting fuse rated 32 V DC with 50 A breaking capacity. The strapped 3.25 A contract is below the 5 A rating and below Eaton's 80% (4 A) continuous recommendation, and 32 V covers the 5.5 V band top. It opens within 1 s at 17.5 A (Eaton 3216FF datasheet p.1).✓
4.8.31D11 (PTVS5V0S1UR)SD_PWRA 5.0 V standoff is adequate for the 3.3 V SD_PWR rail. Cathode is on SD_PWR and anode on GND, so the orientation is consistent (Nexperia PTVSXS1UR datasheet p.4).✓
4.8.32U20 (LMR14050)Net-(C52-Pad1)The R47 51 kΩ / R48 15 kΩ divider with VREF 0.75 V sets 3.300 V. With VREF 0.735-0.765 V and 1% resistors the output spans 3.19-3.42 V, inside the CM4S 3.45 V GPIO bank maximum and the LAN9512 3.0-3.6 V range (TI LMR14050 datasheet p.5; Raspberry Pi CM4S datasheet p.12; SMSC LAN9512 datasheet p.235).✓
4.8.33U20 (LMR14050)Net-(U20-RT/SYNC)R41 82 kΩ gives fSW = (32537/82)^(1/1.045) = 306 kHz (formula p.12), inside the 200-2500 kHz RT range. The 2.2 µs on-time is well above the 75 ns minimum (TI LMR14050 datasheet p.6).✓
4.8.34U20 (LMR14050)Net-(U20-SS)C48 22 nF gives tSS = 22 nF × 0.75 V / 3 µA = 5.5 ms (TI LMR14050 datasheet p.10); the 188 µF output charges at about 0.11 A during soft-start.✓
4.8.35U20 (LMR14050)+5VEN (U20_3) is tied to +5V, the 'tied to VIN' enabled state (TI LMR14050 datasheet p.3). This is a valid auto-enable arrangement, and 5.5 V is far below the 44 V EN absolute maximum.✓
4.8.36U20 (LMR14050)+5VVIN of 4.75-5.5 V is inside the 4-40 V recommended range. The 44 V absolute maximum derated 10% (regulator_input_voltage_pct = 90) permits 39.6 V against 5.5 V applied (TI LMR14050 datasheet p.4).✓
4.8.37U20 (LMR14050), C51GND, Net-(U20-BOOT)GND (U20_7) and the exposed pad U20_9 are on GND as the pin table requires. C51 100 nF 25 V X7R between BOOT and SW meets the 0.1 µF, X5R/X7R, 16 V or higher requirement (TI LMR14050 datasheet p.3, p.20).✓
4.8.38U20, C52-C55, C1 (GRM32EC81C476KE15K)Net-(C52-Pad1), Net-(C1-Pad1)U20 output capacitance is 4 × 47 µF 16 V X6S = 188 µF nominal, the datasheet design example's bank (TI LMR14050 datasheet p.19); DC-bias loss is not applied. Ripple is about 1.2 mV at 0.57 A inductor ripple. 16 V derated 15% (capacitor_voltage_pct = 85) permits 13.6 V against 3.3 V on C52-C55 and C1, so the parts are correctly sized (Murata GRM32EC81C476KE15 datasheet p.2).✓
4.8.39D22 (PDS760Q-13)Net-(D22-K)The catch diode has its cathode on SW and anodes on GND, the correct orientation. 60 V VRRM derated 20% (diode_reverse_voltage_pct = 80) permits 48 V against 5.5 V. Average current is 1.0 A at 5.5 V input against 7 A derated 25% (diode_forward_current_pct = 75), 5.25 A. 0.48 W at 85 °C/W gives about 81 °C junction against the 110 °C limit (Diodes Incorporated PDS760Q datasheet p.2, source: Tomachie).✓
4.8.40R6 (RC1206FR-070R)Net-(C1-Pad1)R6 carries the CM4S 3V3 supply, 0.30 A (P3.3V 1 W, Raspberry Pi CM4S datasheet p.13), against the 2.0 A jumper rated current (Yageo RC1206 datasheet p.6, source: Tomachie).✓
4.8.41U2 (CM4S)+BATT, Net-(C2-Pad1), Net-(C3-Pad1)VBAT at 3.3 V is inside the 2.5-5.25 V operating range. The GPIO bank supplies at 3.19-3.42 V are inside 1.71-3.45 V and below the 3.6 V absolute maximum. C2 and C3 (10 µF) decouple the banks (Raspberry Pi CM4S datasheet p.12).✓
4.8.42U8 (RT9742)3V3_LAN1The 0.28 A load (U9 231 mA plus 42 mA 100BASE-TX magnetics, SMSC LAN9512 datasheet p.237; U10 0.5 mA; LEDs) is inside 0.5 A derated 20% (regulator_output_current_pct = 80), 0.4 A. The 84 mΩ on-resistance at 3.3 V from 'On Resistance vs. Input Voltage' (Richtek RT9742 datasheet p.8, source: Tomachie) gives 23 mV and 6.6 mW, a 1.3 °C rise at 203 °C/W. 3V3_LAN1 is U8's switched copy of +3V3 at 3.3 V.✓
4.8.43U14 (RT9742)Net-(U14-EN)EN (U14_4) is tied to VIN (U14_5), which is +5V through R29. 5.5 V is inside the 0-6 V EN operating range and below the 7 V absolute maximum, so HDMI_5V follows +5V (Richtek RT9742 datasheet p.5, source: Tomachie).✓
4.8.44U13 (RT9742), C41SD_PWRThe output has C41 10 µF, above the 0.01-0.1 µF general bypass (Richtek RT9742 datasheet p.13, source: Tomachie). Its stated 16 V rating derated 15% (capacitor_voltage_pct = 85) permits 13.6 V against 3.3 V.✓
4.8.45U8, U11-U14, U19, U20GNDEvery power IC ground pin (U8_2, U11_2, U12_2, U13_2, U14_2, U19_11, U20_7, U20_9) is on GND, and every VIN pin is on a sourced rail.✓
4.8.46U9 (LAN9512)3V3_LAN1, VDD33A_LAN1The five VDD33IO pins have C13, C19, C22, C25, C28 and C35 (6 × 100 nF), and the seven VDD33A pins have C29-C34 and C36 (7 × 100 nF). This meets the 0.1 µF per pin shown in Figure 2.2 (SMSC LAN9512 datasheet p.27).✓
4.8.47FB1, FB2 (BLM18PG121SH1D)VDD33A_LAN1, Net-(U9A-VDD18ETHPLL)Both are 120 Ω at 100 MHz, 2 A beads as Figure 2.2 calls for (SMSC LAN9512 datasheet p.27). FB2 carries about 0.18 A against 2 A, with 9 mV across its 0.05 Ω maximum DC resistance (Murata BLM18PG datasheet p.1).✓
4.8.48U3-U7, U9, U10, U16+3V3, +5V, 3V3_LAN1Supply ranges are met. TXS0108E: VCCA 3.3 V within 1.4-3.6 V, VCCB 5.5 V top within 1.65-5.5 V. TXB0108: VCCA within 1.2-3.6 V, VCCB within 1.65-5.5 V. SN74LVC1G17: within 1.65-5.5 V. FSUSB42: within 3.0-4.4 V. 93LC66A: within 2.5-5.5 V. LAN9512: within 3.0-3.6 V (TI TXS0108E-Q1 datasheet p.6, TI TXB0108 datasheet p.5, TI SN74LVC1G17 datasheet p.5).✓
4.8.49U3-U6+3V3, +5VVCCA ≤ VCCB holds through power-up and power-down. +5V is present before U20's 5.5 ms soft-start brings up +3V3, and +3V3 collapses with +5V (TI TXS0108E-Q1 datasheet p.6, TI TXB0108 datasheet p.5).✓
4.8.50D4 (1N4007FL), K1 (IM03GR)+5VThe coil flyback diode has its cathode on +5V and anode on Net-(D4-A). 1000 V VRRM covers 5.5 V, and 1 A covers the 28 mA coil current (140 mW at the 5 V coil rating, TE IM03 datasheet p.3). The 5 V coil on +5V matches the part number (AGERTECH 1N4007FL datasheet p.1).✓
4.8.51D5, D7, D8, D21, D23 (SML-M13MTT86)3V3_LAN1, 5V_OTG_1, 5V_OTG_2, +5V, Net-(C52-Pad1)Indicator currents, as V/R bounds, are at most 3.3 mA (D5 via R14 1 kΩ; D23 via R49 1 kΩ) and 3.7 mA (D7, D8, D21 via 1.5 kΩ at 5.5 V), against the 30 mA continuous rating (ROHM SML-M13 datasheet p.1).✓
4.8.52Q6 (2N7002W)USB_BOOT_VBUSThe gate is driven from USB_BOOT_VBUS through R32 1 kΩ, so VGS is at most 5.5 V against 20 V derated 25% (mosfet_vgs_pct = 75), 15 V (onsemi 2N7002W datasheet p.1).✓
4.8.53C37, C38 (CL10B105KP8NNNC)+5VA 10 V part with 5.5 V applied, which its rating meets. Derated 15% (capacitor_voltage_pct = 85) it permits 8.5 V, so it is correctly sized (Samsung CL10B105KP8NNNC datasheet p.1).✓
4.8.54C20, C45 (CL10B105KP8NNNC)+3V3A 10 V part derated 15% (capacitor_voltage_pct = 85) permits 8.5 V with 3.3 V applied, so it is correctly sized.✓
4.8.55C2, C3 (GRM188D71A106MA73D)Net-(C2-Pad1), Net-(C3-Pad1)A 10 V part derated 15% (capacitor_voltage_pct = 85) permits 8.5 V with 3.3 V applied, so it is correctly sized (Murata GRM catalogue p.9).✓
4.8.56C18 (CL10A475KQ8NNNC)VDD18CORE_LAN1The stated 6.3 V rating derated 15% (capacitor_voltage_pct = 85) permits 5.36 V with 1.8 V applied, so it is correctly sized.✓

7.2 Switch DFT Analysis

Switches for mode selection are useful for development and manual debug, but production test environments require electrical override capability. A latching switch (DIP, slide, toggle) holds the signal at the rail it closes onto until somebody moves it, so ATE cannot drive past the contact: it needs a test point and a series isolation resistor between the switch and that rail. A momentary switch (push button) does not hold the signal — the bias resistor sets the level again as soon as the button is released — so it needs only a test point for ATE stimulus access.

IC VCC R_pullup TP SW Rs GND
Design Rationale: Switches for mode selection are valuable for engineering development and bench debug. However, production test and field returns require electrical override capability without manual intervention. Adding test points and isolation resistors creates a lifecycle-robust design that works across development, production test, and field returns without requiring procedure documentation or specialized knowledge of switch positions. The goal is a self-documenting, procedure-proof test interface. BOM impact: One 0201/0402 resistor per controlled signal.
SwitchSignalFunctionPullupRailIssueTest Point?
S1RUNSwitch-controlled signalR4 (100.00K)+3V3 (3.3V)No test point + Switch forces signal, ATE cannot override

7.2.1 Isolation Resistor Options: RUN

Circuit: +3V3 --- R4 (100.00K) --- [signal node/testpoint] --- [switch] --- R_series --- GND. R_series sits on the far side of the switch, so the switch pin never lands on the ground plane. Closing the switch then forms a voltage divider: the IC sees V = Vcc × R_series / (R_pullup + R_series) instead of hard GND. ViL threshold (generic CMOS): 0.990000V max, target 0.841500V (15% margin for resistor tolerance). Verify against device datasheet.

Trade-offs: Lower R_series = more margin below ViL but higher ATE current draw. Higher R_series = lower current but reduced noise margin. Values near 1K-1.5K typically provide good balance for 1.8V signals.

8.2 LSSI DFT Analysis

2 signal(s) missing test point coverage. Test points allow ATE to run tests without requiring operator intervention and setup. They should be considered mandatory for high volume products.
During test, ATE can override functional operation to explicitly test through the interface in ways that functional operation cannot, or is not available at certain test stages.

9 High-Speed Serial Interfaces (HSSI)

24 differential pair(s)

Differential pairs detected from _P/_N naming convention which KiCad uses for differential pair identification. Designer should consider explicit assignment to distinct net classes for each SERDES type to explicitly document layout intent.
2 USB differential pair(s) have no controlled-impedance net class assigned. Assign a 90 Ohm differential net class so the impedance intent carries into PCB layout and length tuning.

9.1 Differential Pairs

Differential pairs with designer-specified class annotations.

7 of 15 differential pairs do not specify a target impedance (the Impedance column is blank). Strongly suggested: put the value in the class name - e.g. 100_OHM.

This section is created by AI and should be reviewed for accuracy. There may be some incorrect analysis, especially if any errors are called out in the Design Summary or Component Value sections. STANDARD MODE — this analysis was produced by the standard model tier.

9.2.1 CM4S USB 2.0 Port and Boot Multiplexer (U2, U16, J7)

AI-Assisted — U2_165 USB_DP and U2_167 USB_DM are a USB 2.0 high-speed (480 Mbps) port. The Raspberry Pi CM4S datasheet (Datasheet) asks for 90 Ω differential routing with P/N matched better than 0.15 mm. The pair runs on USB_P and USB_N to U16 (FSUSB42) pins D+ (U16_3) and D- (U16_4).

U16 sends the pair to one of two places. HSD1 (U16_7, U16_6) carries USB_BOOT_P and USB_BOOT_N to J7_A6/J7_B6 and J7_A7/J7_B7. HSD2 (U16_9, U16_8) carries USB_LAN_P and USB_LAN_N to U9_59 USBDP0 and U9_58 USBDM0. U16 pin O̅E̅ (U16_10) is on GND, so one channel is always connected.

U16 pin SEL is the Q6 drain, pulled up by R31 47 kΩ to +3V3. The Q6 gate takes USB_BOOT_VBUS through R32 1 kΩ, and R35 47 kΩ bleeds USB_BOOT_VBUS to GND, so with no cable the gate returns to ground through 48 kΩ. A host on J7 drives SEL low and selects HSD1. Otherwise SEL sits at 3.3 V less at most 47 mV (1 µA leakage across 47 kΩ) and selects HSD2. This matches the designer's note on sheet USB.

The Fairchild FSUSB42 datasheet (Datasheet) characterises the switch at 480 Mbps. USB 2.0 is DC-coupled with on-die termination, so no series parts are needed and none are fitted. J7 is a USB4205-GF-A Type-C 2.0 receptacle, suitable for 480 Mbps. Its CC pins carry device-side Rd. USB_OTGID is grounded through R51 0 Ω.

9.2.2 LAN9512 Hub Upstream and Downstream Ports (U9, J8)

AI-Assisted — The U9 upstream port USBDP0/USBDM0 is reached only when U16 selects HSD2. U9_63 USBRBIAS sets the high-speed transmit current and the on-chip termination impedance. It has R17, a 12 kΩ 1% resistor to GND, as the SMSC LAN9512 datasheet requires (p.24, Datasheet).

U9_11 VBUS_DET is pulled to 3V3_LAN1 by R16 825 Ω. This is the datasheet's connection for a self-powered hub permanently attached to a host (p.22): the hub asserts its USBDP0 pull-up whenever 3V3_LAN1 is up. When U16 switches to J7, the hub sees a host disconnect.

Downstream port 2 (U9_2 USBDP2 and U9_1 USBDM2 to J8_3 and J8_2) and port 3 (U9_4 USBDP3 and U9_3 USBDM3 to J8_7 and J8_6) run directly to the stacked USB-A receptacle J8 (TE 5787745-1). J8 is appropriate for USB 2.0. There are no series parts, and DC coupling with on-die termination is what USB 2.0 uses.

D26 to D29 sit on these four lines at J8. Port power, the over-current flag wiring and the supply filtering of U9 are covered in the power review and are not repeated here.

9.2.3 HDMI TMDS, DDC, HPD and CEC (U2, D12, D13, D15, J6)

AI-Assisted — U2 drives four TMDS pairs: HDMI_D0, HDMI_D1, HDMI_D2 and HDMI_CLK. They pass flow-through D12 and D13 (RClamp0524PA, Semtech datasheet) to J6, a Würth 685119134923 Type A receptacle. The CM4S datasheet requires 100 Ω pairs, P/N matched better than 0.15 mm and pair-to-pair matched better than 25 mm. TMDS is DC-coupled to the sink's termination, so no series capacitors belong on this board.

HDMI0_SDA and HDMI0_SCL reach J6 with R5 and R58, 4.7 kΩ each, to HDMI_5V. D15 protects HDMI0_SDA, HDMI0_SCL, HDMI0_CEC and HDMI0_HOTPLUG. HDMI0_CEC runs directly to U2_171, whose internal 27 kΩ pull-up to +3.3V serves the line.

HDMI0_HOTPLUG drives only the Q4 gate. Q4 inverts the hot-plug signal into U2_88 HDMI_HPD_N_1V8, which is pulled up internally to 1.8 V through 2.2 kΩ. With no sink attached, nothing defines the Q4 gate level.

The TMDS shield contacts J6_2, J6_5, J6_8 and J6_11 share Net-(J6-CKS) with the shell J6_SH. That net reaches GND only through C44 (1 nF) and R30 (1 MΩ).

9.2.4 Ethernet 100BASE-TX Port and Reference Clock (U9, J4, Y1)

AI-Assisted — U9 drives four lines into J4 (ARJM11D7-009 RJ45 magjack): TXP (U9_55) to J4_1 TD+, TXN (U9_56) to J4_2 TD-, RXP (U9_52) to J4_3 RD+ and RXN (U9_53) to J4_6 RD-. Each line has 49.9 Ω to VDD33A_LAN1 (R55, R56, R57, R36), so each pair sees 100 Ω across it. The centre taps J4_4 and J4_5 are fed through R20 10 Ω with C39 22 nF, which the power review covers. The magnetics provide the transformer coupling that 100BASE-TX requires.

U9_41 AUTOMDIX_EN is pulled up by R18 10 kΩ to 3V3_LAN1, which is the 'tied to VDD33IO' state: Auto-MDIX is enabled (SMSC LAN9512 datasheet p.22). U9_50 EXRES has R19, a 12.4 kΩ 1% resistor to GND, as page 25 requires.

Y1 is a 25 MHz crystal with 18 pF load stated in its description. It has C16 and C17, 33 pF each, and R13 1 MΩ across U9_60 XO and U9_61 XI. With the 3 pF typical XI/XO pin capacitance, the series load is (33 + 3)/2 = 18 pF before PCB stray capacitance is added.

U9_44 CLK24_EN is on GND, which disables CLK24_OUT; that output is unused. U9_34 TEST2 is on GND and U9_40 TEST3 is on 3V3_LAN1, as page 23 requires.

9.3 Observations

AI-Assisted — Three findings sit on the high-speed signal path itself.

First, the ESD9B5.0ST5G parts on the 480 Mbps lines (D14 and D24 at J7, D26 to D29 at J8) are rated 15 pF typical (onsemi datasheet p.2, source: Tomachie). On a 90 Ω pair each line node sees about 22.5 Ω, so 15 pF gives τ = 0.34 ns. That adds about 0.74 ns of 10–90% rise time against a 2.08 ns unit interval. For comparison, the FSUSB42 bandwidth already falls from 720 MHz to 550 MHz with only 5 pF of load. The RClamp0524PA already on the BOM is 0.8 pF maximum line to ground with a 5 V standoff, so it removes this loading.

Second, impedance classes are missing on two sets of nets. USB_BOOT_P and USB_BOOT_N carry the same 480 Mbps signal as USB_P and USB_N but have no 90 Ω class. LAN1_TXP, LAN1_TXN, LAN1_RXP and LAN1_RXN have no 100 Ω class. The CM4S and HDMI pairs are classed correctly.

Third, on J6 the HPD gate has no defined level when no sink is attached, and the TMDS shield contacts have no DC return to GND.

All other high-speed endpoints wire with correct polarity. None of the interfaces reviewed calls for AC-coupling capacitors on this board, and none is fitted.

#InterfaceProtocolFindingSeverity
9.4.1USB boot port (U16 to J7)USB 2.0 High-SpeedUSB_BOOT_P and USB_BOOT_N carry the same 480 Mbps signal through U16 but have no impedance class. Assign the 90 Ω class to both nets (Raspberry Pi CM4S datasheet p.4).Low
9.4.2USB ESD at J7 and J8USB 2.0 High-SpeedD14, D24 (USB_BOOT_N, USB_BOOT_P) and D26, D27, D28, D29 (USB_OTG pairs) are ESD9B5.0ST5G, 15 pF typical at 1 MHz (onsemi datasheet p.2, source: Tomachie). Each adds about 0.74 ns of 10–90% rise time (22.5 Ω × 15 pF × 2.2) against a 2.08 ns unit interval. Replace them with a low-capacitance array such as the RClamp0524PA already used on J6 (0.8 pF maximum line to ground, 5 V VRWM, Semtech RClamp0524PA datasheet p.3).Low
9.4.3HDMI HPDHDMI Hot Plug DetectHDMI0_HOTPLUG carries only the Q4 gate, J6_19 and D15, so with no sink attached the Q4 gate has no defined level. U2_88 HDMI_HPD_N_1V8 (internal 2.2 kΩ to 1.8 V) can then read a false hot-plug. Add a pull-down of about 100 kΩ from HDMI0_HOTPLUG to GND so Q4 is held off when unplugged; the sink-driven level is left essentially unchanged.Low
9.4.4HDMI shield contacts J6HDMI TMDSJ6_2 D2S, J6_5 D1S, J6_8 D0S and J6_11 CKS share Net-(J6-CKS) with the shell J6_SH. That net reaches GND only through C44 1 nF and R30 1 MΩ, so the per-pair TMDS shield contacts have no DC return. Connect J6_2, J6_5, J6_8 and J6_11 to GND and leave only J6_SH on the chassis network.Low
9.4.5Ethernet (U9 to J4)IEEE 802.3u 100BASE-TXLAN1_TXP, LAN1_TXN, LAN1_RXP and LAN1_RXN have no impedance class. Assign a 100 Ω differential class to both pairs, as 100BASE-TX requires.Low
9.4.6USB U2 role strapUSB 2.0 OTGUSB_OTGID is tied to GND through R51 0 Ω, which selects USB host (Raspberry Pi CM4S datasheet, USB_OTGID). The designer's note on sheet USB says the CM4 becomes a device when a cable is plugged into J7. The datasheet permits a grounded ID for a fixed slave with the matching OS driver, so device operation on J7 rests on that driver setting, not on the strap.Review
9.4.7HDMI DDCHDMI DDC (I2C)R5 and R58, 4.7 kΩ to HDMI_5V, pull up HDMI0_SDA and HDMI0_SCL. The CM4S datasheet requires a pull-up per the HDMI specification but states no value (p.16). The HDMI specification range for the source pull-up is 1.5–2.0 kΩ, and 4.7 kΩ is above it.Review
9.4.8HDMI DDC/HPD ESD D15HDMI DDCOperated above a datasheet rating. VRWM for this part is 5 V, below the 5.5 V maximum on HDMI_5V at the DDC pull-ups. However, 5.5 V is still below the breakdown, V_BR(min) 6 V (at 1 mA, 25 C), so the part is not in breakdown. There is leakage at 5.5 V and that leakage is not characterised by the datasheet, which guarantees leakage of 1 µA maximum only up to 5 V; it rises with temperature. The leakage is a shunt that is negligible against the 1.1 mA the 4.7 kΩ pull-ups supply (Semtech RClamp0524PA datasheet p.3).Review
9.4.9Ethernet clock Y125 MHz referenceY1 (FY2500117, 25 MHz, 18 pF load, 15 ppm per its description) has C16 and C17, 33 pF each, and R13 1 MΩ across U9_60 XO and U9_61 XI. The load is (33 + 3)/2 = 18 pF with the 3 pF pin capacitance (SMSC LAN9512 datasheet p.243), before PCB stray capacitance, which raises the load above the crystal's 18 pF. The datasheet's ±50 ppm budget and 50 Ω maximum ESR apply.Review
9.4.10USB (U2 to U16, U16 to U9)USB 2.0 High-SpeedUSB_P, USB_N, USB_LAN_P and USB_LAN_N carry a 90 Ω class, as the CM4S datasheet requires (90 Ω, P/N matched better than 0.15 mm, Raspberry Pi CM4S datasheet p.4).✓

9.4.13USB mux U16 controlUSB 2.0 High-SpeedU16_10 O̅E̅ is on GND, so the switch is enabled and the pin does not float.

10.3 AI-Assisted Analysis

This section is created by AI and should be reviewed for accuracy. There may be some incorrect analysis, especially if any errors are called out in the Design Summary or Component Value sections. STANDARD MODE — this analysis was produced by the standard model tier.

10.3.1 Microwire Configuration EEPROM U10 (93LC66A) on the LAN9512 Hub

AI-Assisted — U10 is a Microchip 93LC66A 4 Kbit Microwire EEPROM, organised as a fixed 512 x 8 because the SOT-23-6 package has no ORG pin. It is the configuration store of the U9 LAN9512 USB hub and Ethernet controller on sheet ETHERNET_LAN1. The datasheets used are the Microchip datasheet at Datasheet and the SMSC LAN9512 datasheet at Datasheet.

The bus is point-to-point on four separate wires: EECS_LAN1, EECLK_LAN1, EEDO_LAN1 into U10 DI, and EEDI_LAN1 from U10 DO. Because DI and DO are not tied together, the bus-conflict resistor the 93LC66A datasheet asks for in that case is not needed.

U10_6 VCC shares 3V3_LAN1 with the U9 VDD33IO pins, so both ends of the bus switch on and off together through U8. The rail sits at about 3.17-3.42 V, which is +3V3 at 3.19-3.42 V less the U8 switch drop. That places U10 in its VCC at or above 2.7 V input-threshold row and in the 2.5-4.5 V timing rows.

U9 clocks EECLK at 0.89-0.90 MHz, and every U9 output window exceeds the corresponding U10 minimum by at least 450 ns. On reads, U10 DO is valid 250 ns at most after a rising edge, which leaves 860 ns before U9 samples on the next rising edge against its 90 ns setup.

R15 (10 kΩ from EECS_LAN1 to GND) holds CS low while U9 is in reset, keeping U10 deselected. On this package, erase and write are enabled and disabled only by the EWEN and EWDS instructions.

10.3.2 microSD Card Socket J5 on the CM4S SDIO Interface

AI-Assisted — J5 is a microSD socket on sheet USD_CARD, wired as a 4-bit SD bus to the SDX pins of the CM4S module socket U2. The memory itself is the removable card, and the SD host controller is on the plug-in CM4S module (Raspberry Pi CM4S datasheet).

The topology is point-to-point with no series termination. Each of the six lines has an ESD9B5.0ST5G bidirectional TVS to GND. The CM4S datasheet lists the SDX signals as available only on CM4Lite, which matches the designer's note "CM4Lite SDCARD I/F" on sheet USD_CARD. U2_2 EMMC_DISABLE_N is left to its internal pull-up, which selects normal boot from the SD card or eMMC.

Card power J5_4 is SD_PWR, the U13 output from the 3.3 V Net-(U13-VIN). SD_PWR carries C41 10 µF, D11 and TP21.

U13 EN and U2 SDX_VDD share the SD_VDD net, which the power review reports is fed only through R28 10 kΩ. For this interface the consequence is direct. SDX_VDD sets the SDIO signalling voltage (CM4S datasheet p.10), while the card is powered from SD_PWR. The I/O bank that the card's CLK, CMD and DAT lines meet therefore has no defined supply.

None of the six SD signal nets carries a pull-up on this board, and the J5_9 card-detect contact is not wired to U2. The 5.0 V TVS standoff is adequate for the 3.42 V maximum signalling level. The 15 pF typical TVS capacitance per line and the 12.5 V clamp level at 1 A both depend on host-side SDX figures.

10.4 Observations

AI-Assisted — The Microwire link between U9 and U10 carries no timing, level or sequencing risk. Its tightest margin is the 860 ns read window against a 90 ns setup, both ends share 3V3_LAN1, and the one level comparison not exactly covered by a datasheet row is bracketed by two rows that both clear the U9 Schmitt thresholds by at least 0.5 V.

The open items on the SD interface all sit on the host side of the module socket. The SDX_VDD feed, already reported in the power review, leaves the SDIO bank without a defined supply while the card is powered. The idle level of CMD and DAT0-DAT3, which have no board pull-ups, rests on the module. The TVS loading and clamp level must also be accepted by the SDX pins.

For test access, none of the four Microwire nets and none of the six SD signal nets carries a test point. U10 can therefore be read or written only through U9, and the SD bus only through the card or the module.

#MemoryInterfaceFindingSeverity
10.5.1U10 (93LC66A)Microwire levels U10 to U9U10_1 DO is specified at two supplies. At VCC 4.5 V it gives VOH 2.4 V minimum at -400 µA and VOL 0.4 V at 2.1 mA; at VCC 2.5 V it gives VOH VCC - 0.2 V = 2.3 V at -100 µA and VOL 0.2 V at 100 µA. U10 runs at about 3.2-3.4 V, between the two stated conditions. Loaded by about 60 µA (the 50 µA EEDI pull-down plus 10 µA leakage), both rows clear the U9 EEDI thresholds (VIHT 1.8 V maximum, VILT 1.01 V minimum) by at least 0.5 V (Microchip 93LC66A datasheet p.3; SMSC LAN9512 datasheet p.238).Review
10.5.2U10 (93LC66A)Microwire test accessNone of EECS_LAN1, EECLK_LAN1, EEDO_LAN1 or EEDI_LAN1 carries a test point, and U10's only signal connections are to U9. Its contents can therefore be read or written only through U9. Add test points on the four nets if the EEPROM is to be programmed or read at board test.Review
10.5.3J5 (microSD)SD host I/O supplyAs the power review reports, U2_6 SDX_VDD is fed only through R28 10 kΩ. SDX_VDD sets the SDIO signalling voltage (Raspberry Pi CM4S datasheet p.10). With the card powered from SD_PWR, the SDX_CLK, SDX_CMD and SDX_D0-SDX_D3 bank therefore has no defined supply when the card drives its lines.Review
10.5.4J5 (microSD)SD bus pull-upsSD_CMD and SD_DAT0-SD_DAT3 have no pull-up resistor on this board, so their idle level during card initialisation depends entirely on the CM4S module. Check that the module defines these levels; if it does not, fit pull-ups from each line to SD_PWR.Review
10.5.5J5 (microSD)SD card detectThe J5_9 card-detect contact is not wired to U2, so card insertion and removal are not signalled in hardware; this is a permitted choice. U2 GPIO32, whose ALT4 function is SD_CARD_PRES, could provide a card-present input if detection is wanted (Raspberry Pi CM4S datasheet).Review
10.5.6J5 (microSD)SD clock terminationSD_CLK runs from U2_10 directly to J5_5 with no series resistor, and the CM4S datasheet states no termination requirement for SDX_CLK. Whether a source-series resistor is needed depends on the routed length at layout.Review
10.5.7J5 (microSD)SD ESD loadingEach SD line carries 15 pF typical (0 V, 1 MHz) from its ESD9B5.0ST5G (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). Check that the U2 SDX host's maximum bus capacitance at the SD clock rate in use accommodates it. The maximum SDX bus load value was not available at report generation time.Review
10.5.8J5 (microSD)SD ESD clampD9, D10, D32, D33, D34 and D35 clamp at 12.5 V maximum at 1 A and 15.0 V at 2 A (8/20 µs, 25 °C) (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). Check that the U2 SDX pins are rated for this waveform.Review
10.5.9U10 (93LC66A)Microwire to U9Point-to-point wiring on separate nets: U9_24 EECS to U10_5 CS, U9_23 EECLK to U10_4 SCLK, U9_25 EEDO to U10_3 DI, and U10_1 DO to U9_26 EEDI. DI and DO are not tied, so the DI-DO bus-conflict resistor is not required (Microchip 93LC66A datasheet p.6; SMSC LAN9512 datasheet p.21).✓
10.5.10U10 (93LC66A)Microwire supplyU10_6 VCC is on 3V3_LAN1 at 3.17-3.42 V, inside the 2.5-5.5 V VCC range. It shares the rail with U9 VDD33IO (3.0-3.6 V), so both bus ends power up and down together through U8 (Microchip 93LC66A datasheet p.1; SMSC LAN9512 datasheet p.235).✓
10.5.11U10 (93LC66A)Microwire supply3V3_LAN1 carries six 100 nF capacitors (C13, C19, C22, C25, C28, C35), one more than the five U9 VDD33IO pins, so U10 shares that local decoupling.✓
10.5.12U10 (93LC66A)Microwire clockEECLK period is 1110-1130 ns (0.89-0.90 MHz) against the 2 MHz maximum. High and low times are 550 ns minimum against the 250 ns and 200 ns minimums (SMSC LAN9512 datasheet p.241; Microchip 93LC66A datasheet p.4, 2.5 V ≤ VCC < 5.5 V).✓
10.5.13U10 (93LC66A)Microwire chip selectEECS is high 1070 ns minimum before EECLK rises, against TCSS 100 ns (2.5 V ≤ VCC < 4.5 V). EECS low time is 1070 ns minimum against TCSL 250 ns (SMSC LAN9512 datasheet p.241; Microchip 93LC66A datasheet p.4).✓
10.5.14U10 (93LC66A)Microwire write dataEEDO is valid 550 ns before and held 550 ns after the EECLK rising edge, against the U10 DI setup TDIS 100 ns and hold TDIH 100 ns minimums (SMSC LAN9512 datasheet p.241; Microchip 93LC66A datasheet p.4).✓
10.5.15U10 (93LC66A)Microwire read dataU10 DO is valid 250 ns maximum after a rising edge (TPD, 2.5 V ≤ VCC < 4.5 V, CL = 100 pF). This leaves 860 ns before U9 samples EEDI on the next rising edge, against its 90 ns setup and 0 ns hold (Microchip 93LC66A datasheet p.4; SMSC LAN9512 datasheet p.241).✓
10.5.16U10 (93LC66A)Microwire levels U9 to U10U9 O8 outputs give VOH ≥ VDD33IO - 0.4 V = 2.77 V and VOL ≤ 0.4 V at 8 mA. These meet the U10 VIH of 2.0 V minimum and VIL of 0.8 V maximum (VCC ≥ 2.7 V), and both parts share 3V3_LAN1, so the VCC + 1 V input maximum is not approached (SMSC LAN9512 datasheet p.238; Microchip 93LC66A datasheet p.3).✓
10.5.17U10 (93LC66A)Microwire chip select idleR15 10 kΩ, from EECS_LAN1 to GND, holds U10_5 CS low while U9 is in reset. The datasheet states this deselects the device and holds its control logic in reset. The 0.33 mA it draws when EECS is high is well inside the 8 mA O8 drive (Microchip 93LC66A datasheet; SMSC LAN9512 datasheet p.242).✓
10.5.18U10 (93LC66A)Microwire data out idleU10_1 DO is high-Z outside reads, and the internal 50 µA pull-down on U9_26 EEDI defines the level on EEDI_LAN1 (Microchip 93LC66A datasheet; SMSC LAN9512 datasheet pp.21, 31).✓
10.5.19U10 (93LC66A)Microwire environmentThe 93LC66AT-I industrial grade (-40 °C to +85 °C) matches the U9 LAN9512i industrial range (-40 °C to +85 °C) (Microchip 93LC66A datasheet p.1; SMSC LAN9512 datasheet p.235).✓
10.5.20J5 (microSD)SD 4-bit to U2The 4-bit SD bus is wired one to one: U2_10 SDX_CLK to J5_5 CLK, U2_12 SDX_CMD to J5_3 CMD, and U2_16, U2_18, U2_22, U2_24 (SDX_D0-SDX_D3) to J5_7 DAT0, J5_8 DAT1, J5_1 DAT2 and J5_2 DAT3/CD (Raspberry Pi CM4S datasheet).✓
10.5.21J5 (microSD)SD card powerJ5_4 VDD is on SD_PWR, the U13 output from the 3.3 V Net-(U13-VIN). J5_6 VSS and the shell contacts J5_S1-J5_S4 are on GND.✓
10.5.22J5 (microSD)SD ESD standoffD9, D10, D32, D33, D34 and D35 (ESD9B5.0ST5G) have a 5.0 V standoff, which is adequate for the 3.42 V maximum of the 3.3 V SD signalling. They are rated for ±18 kV IEC 61000-4-2 contact discharge (onsemi ESD9B5.0S datasheet pp.1-2, source: Tomachie).✓

10.5.24J5 (microSD)SD boot sourceU2_2 EMMC_DISABLE_N has no strap and is shared only with the Q1 drain, so its internal 10 kΩ pull-up selects 'boot from SD card or eMMC (normal boot)' (Raspberry Pi CM4S datasheet p.13).✓

11.2 Functional Analysis

This section is created by AI and should be reviewed for accuracy. There may be some incorrect analysis, especially if any errors are called out in the Design Summary or Component Value sections. STANDARD MODE — this analysis was produced by the standard model tier.

11.2.1 Ethernet Crystal Y1

AI-Assisted — Y1 (FY2500117, 25 MHz AT-cut fundamental) sits across U9_61 XI and U9_60 XO. C16 and C17, 33 pF each, go from those pins to GND, R13 1 MΩ is across the crystal, and the Y1 case pins 2 and 4 are on GND. Load-capacitance matching is covered in the signal-integrity review and is not repeated here.

The remaining figures are compared with the LAN9512 crystal requirements (SMSC LAN9512 datasheet p.243, Datasheet). Y1's 50 Ω maximum ESR equals the 50 Ω limit. Its 300 µW maximum drive level meets the 300 µW minimum the LAN9512 asks of the crystal. Its 5 pF maximum shunt capacitance is below the 7 pF typical figure.

The frequency budget is 20 ppm calibration, plus 20 ppm stability, plus 5 ppm first-year aging, giving 45 ppm (FY2500117 datasheet p.3, source: Tomachie). This is inside the ±50 ppm IEEE 802.3u transmit budget and matches the approximately ±45 ppm combination the LAN9512 note asks for. The schematic description states 15 ppm, which does not match the 20 ppm calibration and stability figures of the fitted part number. The -40 to +85 °C operating range equals the LAN9512i industrial crystal range.

11.2.2 USB Switch U16

AI-Assisted — U16 (FSUSB42) is supplied from +3V3 at 3.19 to 3.42 V, inside its 3.0 to 4.4 V recommended range, with C45 1 µF at U16_1. U16_3 and U16_4 carry the CM4S USB pair. HSD1 goes to the J7 boot port and HSD2 goes to the U9 hub upstream port.

The SEL and O̅E̅ levels are settled in the signal-integrity review. The behaviour they give matches the designer's note on sheet USB: with USB_BOOT_VBUS present, Q6 pulls U16_2 SEL low and the CM4S reaches J7; otherwise R31 holds SEL high and the CM4S reaches the LAN9512.

J7 can be powered by an external host while +3V3 is off. The FSUSB42 power-off leakage is ±2 µA maximum on all I/O ports at VCC 0 V with VSW 0 to 4.3 V (Fairchild FSUSB42 datasheet p.4, Datasheet). An attached host therefore does not back-power the switch. The -0.5 to 4.5 V switch I/O range covers USB 2.0 signalling.

Q6 only pulls SEL toward GND, and R31 returns SEL to +3V3 itself. SEL therefore never exceeds the VCC-referenced control-input absolute maximum, including while +3V3 is off.

11.2.3 Compute Module U2: Straps, Unused Pins and Firmware Dependencies

AI-Assisted — U2_38 E̅E̅P̅R̅O̅M̅_W̅P̅ is unconnected. The module's internal 100 kΩ pull-up to GPIO28-45_VDD therefore leaves the bootcode EEPROM writable permanently. The CM4S datasheet recommends grounding this pin in final products (Raspberry Pi CM4S datasheet).

The recommended remedy is to route U2_38 to a spare U2 GPIO in the 28-45 bank, such as the GPIO44 (TP17) or GPIO45 (TP18) net, with a 10 kΩ pull-down. That pull-down gives 3.42 V × 10/110 = 0.31 V, below the 0.8 V VIL. The EEPROM is then protected by default, and firmware raises the GPIO only for an update.

U2_189 and U2_190 VDAC sit on the 3.3 V supply through R9, which the datasheet permits when TVDAC is unused; U2_166 TVDAC is open. U2_179 VDD_CORE, the VideoCore JTAG pins, the DSI and CAM pins, and the NC pins are all left unconnected, which is permitted. Pins 183 to 186 may be unconnected or tied to 1.8 V.

In the U2 symbol, U2_5 GPIO1 and U2_6 SDX_VDD are typed as power outputs. The datasheet defines GPIO1 as a GPIO and SDX_VDD as a power input, and this typing hides the unsourced SDX_VDD from electrical rule checking.

GPIO0 and GPIO1 carry the U19 I2C bus through R52 and R53, with R43 and R44 3.3 kΩ pull-ups to +3V3. The datasheet reserves these pins for HAT ID. It asks for force_eeprom_read=0 in config.txt when they are not used for that purpose. The USB interface the hub and boot port depend on is disabled by default and needs otg_mode=1 in config.txt.

On the I2C bus, the CM4S VOL of 0.4 V maximum equals the HUSB238 VIL of 0.4 V maximum. The CM4S figure carries no stated test current, and the pull-ups ask the pin to sink up to 1.04 mA.

11.2.4 Reset Network on RUN and Indicator D3

AI-Assisted — RUN (U2_177) has three connections. R4 100 kΩ pulls it up to +3V3. S1 shorts it to GND as the reset button, a use the datasheet allows. D2 (ESD9B3.3ST5G) clamps it to GND.

D2 is operated above a datasheet rating. VRWM for this part is 3.3 V, below the 3.42 V maximum on the rail. However, 3.42 V is still below the breakdown, V_BR(min) 5.0 V (at 1.0 mA, 25 °C), so the part is not in breakdown. There is leakage at 3.42 V and that leakage is not characterised by the datasheet, which guarantees leakage of 100 nA maximum only up to 3.3 V; it rises with temperature (onsemi ESD9B datasheet p.2, source: Tomachie). The leakage is a shunt in parallel with the module's internal 10 kΩ pull-up and R4. Even at microamps it moves the RUN high level by millivolts, so this is a spec-margin note. The ESD9B5.0ST5G already on the board restores the leakage guarantee, at a 12.5 V rather than 10.5 V clamp at 1 A.

Q3 (BSS84AK) has its source on +3V3 and its gate on RUN. It lights D3 (red) through R7 1 kΩ while RUN is low. This gives a gate drive of -3.3 V against a VGS(th) of -1.1 to -2.1 V (NXP BSS84AK datasheet p.6, Datasheet). With RUN high, VGS is 0 V and D3 is off.

The D3 current is at most (3.42 - 1.6)/1 kΩ = 1.8 mA, using the 1.6 V minimum forward voltage. This is against a 30 mA continuous rating, and D3 sees no reverse voltage (ROHM SML-M13UTT86 datasheet p.3, source: Tomachie).

11.2.5 Boot-Mode Stage Q1 and Q2 with ACT LED D1

AI-Assisted — Q1 and Q2 (2N7002W) are in series from EMMC_DISABLE_N to GND, forming an AND. EMMC_DISABLE_N is pulled low, forcing USB boot, only when both of these hold: J1 bridges pins 1-2 (the designer's "Boot position") with USB_BOOT_VBUS present, and the module holds EMMC_EN_N_1V8 high, meaning it is not accessing the SD card or eMMC. D1 with R2 1 kΩ from +3V3 lights whenever Q2 conducts.

Q1 is correctly applied. Its gate sees at most 5.5 V from USB_BOOT_VBUS, against the 20 V VGS rating derated 25% (mosfet_vgs_pct = 75) to 15 V. J1 pins 2-3 ground the gate, and R1 47 kΩ holds it low with no jumper fitted. Its open drain meets the CM4S requirement that EMMC_DISABLE_N be driven open-collector.

Q2 is the problem. Its gate is held only by the module's internal 2.2 kΩ pull-up to 1.8 V. The 2N7002W VGS(th) is 1.0 V minimum to 2.0 V maximum at 250 µA (onsemi 2N7002W datasheet p.2, Datasheet). At the 2.0 V end of that band, a 1.8 V gate does not reach even 250 µA. Q2 is therefore not assured to sink the D1 current of up to 1.8 mA, nor the 0.34 mA from the EMMC_DISABLE_N internal 10 kΩ pull-up. Both the ACT LED and the forced USB boot depend on it.

The fix is a part change with the topology kept: an N-MOSFET whose maximum VGS(th) is well below 1.8 V and whose RDS(on) is specified at VGS 1.8 V. D1 itself carries at most 1.8 mA against its 30 mA rating.

11.2.6 USB Hub and Ethernet Controller U9 with FDX LED D6

AI-Assisted — The U9 pins without an active function are handled as the LAN9512 datasheet requires (SMSC LAN9512 datasheet pp.21-25). U9_12 R̅E̅S̅E̅T̅ is tied high through R12 10 kΩ to 3V3_LAN1, as permitted when unused, and the internal 22 ms power-on reset applies. U9_28 T̅R̅S̅T̅, U9_29 TMS, U9_30 TDI and U9_32 TCK are tied to 3V3_LAN1, and U9_31 TDO is open. U9_13 TEST1 and U9_47 TEST4 are open, as are the six NC pins. GPIO3 to GPIO7 are open, held by their internal pull-ups.

nFDX_LAN1 sinks D6 (red) from VDD33A_LAN1 through R23 330 Ω. The current is (3.42 - 2.0)/330 = 4.3 mA at the 2.0 V typical forward voltage, inside the 8 mA IOL at which VOL is 0.4 V. The J4 link and speed LEDs use R21 and R22 330 Ω, with a V/R ceiling of 10.4 mA before their forward drop.

PRTCTL2_OTG_1 and PRTCTL3_OTG_2 drive U11_4 and U12_4 EN with no external pull-up. Port power is enabled only by the U9 internal 50 µA pull-up, and the LAN9512 datasheet p.242 states an external resistor must be added for a load that must be pulled high.

LAN1_EN connects U2_30 GPIO29 to U8_4 EN with no resistor. The CM4S datasheet states no default pull for GPIO29, so U8 EN floats until firmware configures the pin. The RT9742 EN pin must not float (Richtek RT9742 datasheet, source: Tomachie).

11.2.7 Relay K1 and Driver Q5

AI-Assisted — K1 (IM03GR, 5 VDC coil, 178 Ω) has its coil between +5V and Net-(D4-A), which Q5 (2N7002W) switches to GND. D4 provides the flyback path; it is passed in the power review.

The coil current is at most 5.5 V / 160 Ω = 34.4 mA, using the -10% coil resistance. At the 4.75 V minimum of +5V, the coil sees about 4.5 V after the drop across Q5, above the 3.75 V operate voltage (TE IM03 datasheet p.3, Datasheet). At 5.5 V the coil dissipates 170 mW against the 140 mW rated coil power. That gives a 26 K rise at 150 K/W, putting the coil at about 66 °C from a 40 °C ambient.

RELAY1 is driven by U2_28 GPIO28, whose default pull the CM4S datasheet does not state. R11 100 kΩ to GND therefore keeps the relay released through reset. The minimum GPIO high level, 3.19 - 0.4 = 2.79 V, exceeds the 2.0 V maximum VGS(th) of Q5.

Q5 carries 34.4 mA against 106 mA continuous at 40 °C, derated 30% (mosfet_id_pct = 70) to 74 mA. Its off-state VDS is under 7 V against 60 V derated 25% (mosfet_vds_pct = 75) to 45 V (onsemi 2N7002W datasheet p.1).

The second pole, K1 pins 2 to 4, is unused and left open. Pins 5 to 7 reach J3 with each contact doubled across two J3 pins. Release time with the parallel diode is 5 ms maximum.

11.2.8 USB-PD Load Switch Q7

AI-Assisted — Q7 (AONR21307, P-channel) has its source on the fused VBUS, Net-(Q7-S1), and its drain on +5V through R45. Its body diode therefore blocks input-to-load current when the gate is off.

The HUSB238 variant fitted turns GATE on at power-on reset (Hynetek HUSB238 datasheet p.15, source: Tomachie). With VSET strapped to 5 V, that delivers only the 5 V default.

At the 4.75 V minimum VBUS, the gate divider gives VGS = 4.75 × 51/(51 + 5.1 + 0.3) = 4.30 V, using the 300 Ω typical GATE pull-low impedance. Figure 5 (p.3) gives about 15.9 mV/A, i.e. 15.9 mΩ, typical at 4.3 V and 25 °C. Scaled by the 18.5/14.7 maximum-to-typical ratio and by 1.13 for 60 °C from Figure 4 (p.3), that is about 22.6 mΩ maximum. At the 3.25 A contract current this gives 3.25² × 0.0226 = 0.24 W. With the 55 °C/W steady-state θJA, the junction reaches 40 + 0.24 × 55 = 53 °C, well below the 110 °C junction limit (AOS AONR21307 datasheet pp.1-3, Datasheet).

The drain current of 3.25 A compares with 17 A at 25 °C and 14 A at 70 °C. Derated 30% (mosfet_id_pct = 70), those ratings permit 11.9 A and 9.8 A. The DC curve of Figure 9 (p.4) allows about 20.5 A at 5.5 V VDS.

11.2.9 USB-C Power Port Data Lines (J9, U19)

AI-Assisted — On J9, USB_D+ (J9_A6, J9_B6) and USB_D- (J9_A7, J9_B7) reach only U19 pins D+ and D-. U19 uses these pins for Apple Divider 3 and BC1.2 charger detection (Hynetek HUSB238 datasheet p.1, source: Tomachie). No 480 Mbps traffic crosses J9, so 90 Ω routing does not apply to these nets. The HUSB238 D+/D- absolute maximum is 12 V, above any level the port can present. D19 and D20 add 15 pF each, which is harmless at detection rates. U19 supplies the CC pull-downs internally; its configuration is covered in the power review.

11.3 Findings

AI-Assisted —
#DeviceFindingSeverity
11.3.1Q2 (2N7002W)The Q2 gate sees only 1.8 V, from the module's internal 2.2 kΩ pull-up on EMMC_EN_N_1V8, against VGS(th) of 1.0-2.0 V at 250 µA. At the 2.0 V maximum, Q2 does not reach the threshold current. Neither the D1 ACT LED current (up to 1.8 mA) nor the 0.34 mA EMMC_DISABLE_N pull-down for forced USB boot is assured. Fit an N-MOSFET with VGS(th) maximum well below 1.8 V and RDS(on) specified at VGS 1.8 V, keeping the topology (onsemi 2N7002W datasheet p.2).Medium
11.3.2U2 (CM4S)U2_38 E̅E̅P̅R̅O̅M̅_W̅P̅ is unconnected, so the internal 100 kΩ pull-up leaves the bootcode EEPROM permanently writable; the datasheet recommends grounding it in final products. Route U2_38 to a spare U2 GPIO (e.g. GPIO44/TP17 or GPIO45/TP18) with a 10 kΩ pull-down: 3.42 V × 10/110 = 0.31 V, below the 0.8 V VIL. The EEPROM is then protected by default, and firmware raises the GPIO only for an update (Raspberry Pi CM4S datasheet p.14).Low
11.3.3U9 (LAN9512), U11, U12PRTCTL2_OTG_1 and PRTCTL3_OTG_2 drive U11_4 and U12_4 EN using only the U9 internal 50 µA pull-up. The LAN9512 datasheet p.242 states an external resistor must be added for a load that must be pulled high. Add a 10 kΩ pull-up from each net to 3V3_LAN1; PRTCTL sinks 0.34 mA when disabling port power.Low
11.3.4U8 (RT9742), U2 (CM4S)LAN1_EN connects U2_30 GPIO29, which has no default pull stated (CM4S datasheet p.5), to U8_4 EN, which must not float (Richtek RT9742 datasheet, source: Tomachie). U8 EN is therefore undefined until firmware configures GPIO29. Add a 100 kΩ pull-down from LAN1_EN to GND so U9 stays unpowered until firmware enables it.Low
11.3.5Y1 (FY2500117)The schematic description states 15 ppm, but the FY2500117 datasheet gives 20 ppm calibration and 20 ppm stability. Correct the description to match the fitted part.Review
11.3.6U2 (CM4S)The U2 symbol types U2_5 GPIO1 and U2_6 SDX_VDD as power outputs. The datasheet defines GPIO1 as a GPIO and SDX_VDD as a power input. Correct the pin types so electrical rule checking reports an unsourced SDX_VDD.Review
11.3.7U2 (CM4S)GPIO0 and GPIO1 carry the U19 I2C bus, not a HAT ID EEPROM. The datasheet asks for force_eeprom_read=0 in config.txt in that case (CM4S datasheet, GPIO0/GPIO1).Review
11.3.8U2 (CM4S)The USB interface feeding U16, the J7 boot port and the U9 hub is disabled by firmware by default. It needs otg_mode=1 in config.txt (CM4S datasheet, USB_DP).Review
11.3.9U2 (CM4S), U19The CM4S VOL of 0.4 V maximum equals the HUSB238 VIL of 0.4 V maximum, leaving no margin. The CM4S VOL carries no stated test current, while R43/R44 3.3 kΩ require up to 1.04 mA. Check that the CM4S VOL at 1.04 mA stays at or below 0.4 V.Review
11.3.10D2 (ESD9B3.3ST5G)Operated above a datasheet rating. VRWM for this part is 3.3 V, below the 3.42 V maximum on RUN. However, 3.42 V is still below the breakdown, V_BR(min) 5.0 V (at 1.0 mA, 25 °C), so the part is not in breakdown. There is leakage at 3.42 V and that leakage is not characterised by the datasheet, which guarantees leakage of 100 nA maximum only up to 3.3 V; it rises with temperature. The leakage is a small shunt beside the RUN pull-ups. The ESD9B5.0ST5G restores the guarantee, at a 12.5 V rather than 10.5 V clamp at 1 A (onsemi ESD9B datasheet p.2, source: Tomachie).Review
11.3.11U9 (LAN9512), J4nLNKA_LAN1 and nSPD_LAN1 sink the J4 LEDs through R21 and R22 330 Ω, with a V/R ceiling of 10.4 mA. Check that the J4 LED forward voltage keeps each current within the U9 pin's 8 mA IOL. The J4 LED forward voltage was not available at report generation time.Review
11.3.12K1 (IM03GR)Coil dissipation is 5.5²/178 = 170 mW, giving a 26 K rise at 150 K/W and about 66 °C coil temperature from a 40 °C ambient (TE IM03 datasheet pp.3-4).Review
11.3.13Y1 (FY2500117)ESR is 50 Ω maximum, equal to the LAN9512 50 Ω limit (FY2500117 datasheet p.3, source: Tomachie; SMSC LAN9512 datasheet p.243).✓
11.3.14Y1 (FY2500117)The 300 µW maximum drive level meets the 300 µW minimum the LAN9512 asks of the crystal. The 5 pF maximum shunt capacitance is below the 7 pF typical figure (LAN9512 datasheet p.243).✓
11.3.15Y1 (FY2500117)Frequency budget is 20 ppm calibration + 20 ppm stability + 5 ppm aging = 45 ppm. This is inside the ±50 ppm IEEE 802.3u budget and matches the approximately ±45 ppm combination in LAN9512 Note 5.13 (p.243).✓
11.3.16Y1 (FY2500117)The -40 to +85 °C operating range matches the LAN9512i industrial crystal range (LAN9512 datasheet p.243).✓
11.3.17U16 (FSUSB42)VCC from +3V3 at 3.19-3.42 V is inside the 3.0-4.4 V recommended range, with C45 1 µF local bypass at U16_1 (Fairchild FSUSB42 datasheet p.3).✓
11.3.18U16 (FSUSB42)Power-off leakage is ±2 µA maximum at VCC 0 V with VSW 0-4.3 V, so a host on J7 does not back-power U16 while +3V3 is off. The switch I/O range of -0.5 to 4.5 V covers USB 2.0 signalling (FSUSB42 datasheet pp.3-4).✓
11.3.19U16 (FSUSB42)Q6 only pulls U16_2 SEL toward GND, and R31 returns it to +3V3. SEL never exceeds the VCC-referenced control-input absolute maximum, including with +3V3 off (FSUSB42 datasheet p.3).✓
11.3.20U2 (CM4S)U2_189 and U2_190 VDAC are on the 3.3 V supply through R9, with U2_166 TVDAC unused; the datasheet permits 3.3 V on VDAC when TV-out is unused (CM4S datasheet, VDAC pin description).✓
11.3.21U2 (CM4S)U2_179 VDD_CORE, the VideoCore JTAG pins, the DSI and CAM pins, and NC pins 124-162 and 183-186 are left unconnected. All are permitted states; pins 183-186 may be unconnected or tied to 1.8 V (CM4S datasheet pin table).✓
11.3.22U2 (CM4S), U19HUSB238 SDA VOL of 0.4 V at 2 mA is below the CM4S 0.8 V VIL. CM4S VOH of at least 2.79 V exceeds the HUSB238 1.4 V VIH. 3.42 V is below the 6 V SDA/SCL absolute maximum (CM4S datasheet p.12; Hynetek HUSB238 datasheet pp.5, 7, source: Tomachie).✓
11.3.23U2 (CM4S), S1, R4RUN is held high by R4 100 kΩ to +3V3 and the internal 10 kΩ pull-up. S1 drives it low to reset the module, which the datasheet permits (CM4S datasheet, RUN).✓
11.3.24Q3 (BSS84AK)With RUN low the gate drive is -3.3 V, beyond the -1.1 to -2.1 V VGS(th) band. With RUN high VGS is 0 V and D3 is off (NXP BSS84AK datasheet p.6).✓
11.3.25D1, D3 (SML-M13UTT86)Forward current is at most (3.42 - 1.6)/1 kΩ = 1.8 mA against the 30 mA continuous rating, with no reverse stress in either state (ROHM SML-M13UTT86 datasheet p.3, source: Tomachie).✓
11.3.26Q1 (2N7002W)Gate is driven from USB_BOOT_VBUS through J1 pins 1-2, at most 5.5 V against 20 V derated 25% (mosfet_vgs_pct = 75) to 15 V. J1 pins 2-3 or R1 47 kΩ hold it off. The open drain meets the open-collector requirement on EMMC_DISABLE_N (onsemi 2N7002W datasheet pp.1-2; CM4S datasheet).✓
11.3.27Q1, Q2 (2N7002W)Q1 and Q2 in series form an AND: EMMC_DISABLE_N is forced low only with J1 in the boot position, VBUS present and EMMC_EN_N_1V8 high. This matches the CM4S typical FET connection; the topology is correct as drawn.✓
11.3.28U9 (LAN9512)U9_12 R̅E̅S̅E̅T̅ is tied high through R12 10 kΩ to 3V3_LAN1, as the datasheet requires when unused (SMSC LAN9512 datasheet pp.21, 240).✓
11.3.29U9 (LAN9512)U9_28 T̅R̅S̅T̅ is tied to 3V3_LAN1, as required when unused. U9_29 TMS, U9_30 TDI and U9_32 TCK, which have no internal pull, are tied to 3V3_LAN1. U9_31 TDO is open (LAN9512 datasheet p.21).✓
11.3.30U9 (LAN9512)U9_13 TEST1, U9_47 TEST4 and NC pins U9_6-U9_9, U9_17 and U9_18 are left unconnected, as required (LAN9512 datasheet pp.23, 25).✓
11.3.31U9 (LAN9512)U9_35-U9_37, U9_42 and U9_43 (GPIO3-GPIO7) are open and held by their internal 50 µA pull-ups (LAN9512 datasheet pp.22, 31).✓
11.3.32U9 (LAN9512), D6nFDX_LAN1 sinks D6 through R23 330 Ω from VDD33A_LAN1: (3.42 - 2.0)/330 = 4.3 mA, inside the 8 mA IOL at which VOL is 0.4 V. D6 lights for full duplex (LAN9512 datasheet pp.21, 238; Lumex SML-LXFM0603SIC datasheet p.1, Datasheet).✓
11.3.33K1 (IM03GR)At the 4.75 V minimum of +5V, the coil sees about 4.5 V after Q5, above the 3.75 V operate voltage. The 5 VDC coil (178 Ω) suits the +5V rail (TE IM03 datasheet p.3).✓
11.3.34Q5 (2N7002W), R11GPIO28 has no default pull stated, so R11 100 kΩ to GND holds the Q5 gate low and K1 released through reset. The minimum GPIO high level of 2.79 V exceeds the 2.0 V maximum VGS(th) (CM4S datasheet p.5; onsemi 2N7002W datasheet p.2).✓
11.3.35Q5 (2N7002W)The coil current of at most 34.4 mA is inside 106 mA continuous at 40 °C, derated 30% (mosfet_id_pct = 70) to 74 mA. Off-state VDS of under 7 V is inside 60 V derated 25% (mosfet_vds_pct = 75) to 45 V (onsemi 2N7002W datasheet p.1).✓
11.3.36K1 (IM03GR)The second pole (K1 pins 2-4) is unused and left open. The switched pole reaches J3 on doubled contacts for RELAY1_COM, RELAY1_NO and RELAY1_NC.✓
11.3.37Q7 (AONR21307)Source is on the fused VBUS and drain on +5V, so the body diode blocks input-to-load current with the gate off. The 001DD GATE turn-on at power-on reset delivers only the strapped 5 V default (AOS AONR21307 datasheet p.2; Hynetek HUSB238 datasheet p.15, source: Tomachie).✓
11.3.38Q7 (AONR21307)At 4.75 V VBUS, VGS is 4.30 V. Figure 5 (p.3) gives about 15.9 mΩ typical, which scales to about 22.6 mΩ maximum at 60 °C using Figure 4 (p.3). Loss at 3.25 A is 0.24 W, and the junction reaches 53 °C at 55 °C/W from 40 °C, against the 110 °C junction limit.✓
11.3.39Q7 (AONR21307)3.25 A against 17 A (25 °C) and 14 A (70 °C) ambient ratings, derated 30% (mosfet_id_pct = 70) to 11.9 A and 9.8 A. The Figure 9 (p.4) DC SOA allows about 20.5 A at 5.5 V VDS.✓

13.3 EMC & ESD Analysis

This section is created by AI and should be reviewed for accuracy. There may be some incorrect analysis, especially if any errors are called out in the Design Summary or Component Value sections. STANDARD MODE — this analysis was produced by the standard model tier.

13.3.1 EMC Architecture and Grounding

AI-Assisted — The board has two ground domains, logic GND and chassis Earth. Earth enters only at J4_13, the magjack chassis contact. It returns to GND through C40, 1 nF rated 2 kV, in parallel with R26, 1 MΩ. This is a deliberate high-impedance bond. The capacitor gives the strike edge one chosen entry point, and the resistor bleeds static and breaks the DC and mains-frequency loop between a panel-mounted shell, protective earth and logic GND.

The cable connectors repeat this pattern. J6 uses its own shell net, Net-(J6-CKS), bonded by C44 and R30. J7 and J8 share Net-(J7-SHIELD), bonded by C56 and R54. All three bonds use the same 1 nF 2 kV and 1 MΩ pair. The J9 and J5 shells sit on GND directly.

Mounting holes H1 to H4 are on GND. On an earthed metal enclosure with conductive standoffs, they would make the GND-to-chassis connection that the RC bonds are meant to control.

The review is judged at the professional level, for an industrial product. Immunity follows IEC 61000-6-2: ESD per IEC 61000-4-2 at 4 kV contact and 8 kV air, EFT per IEC 61000-4-4, and surge per IEC 61000-4-5 on long signal cables. Emissions follow IEC 61000-6-4 and CISPR 32. None of the connector signal paths reviewed carries a common-mode choke or ferrite, so emission control rests on the controlled-impedance pairs and the shield bonds. Every ESD figure quoted is at 25 °C, and the design states no maximum ambient.

13.3.2 USB-C Power Input J9

AI-Assisted — J9 is the externally accessible USB-PD power receptacle. Each signal contact has an ESD9B5.0ST5G clamp to logic GND: D16 and D17 on CC1 and CC2, and D19 and D20 on D+ and D-. All four lines end at U19 (HUSB238).

Of the three Type-C checks, two are met. The GND contacts are hard on GND, and every clamp references logic GND rather than a shield net. The symbol carries no mid-plate pin. The third check is not met, because J9_S1 SHIELD sits on GND.

U19 rates CC1 and CC2 at 25 V so that a cable fault shorting CC to VBUS is survivable. With D16 and D17 fitted, the CC lines instead tolerate only up to the D16/D17 breakdown of 5.8 to 7.8 V. At the strapped 5 V contract, with a 5.5 V maximum, a CC-to-VBUS short stays below V_BR(min) of 5.8 V.

The D18 VBUS clamp, its placement and its standoff are covered by the power review.

The power review names F1, Q7 and R45 as the series elements between J9 VBUS and U20. None of them is a filter element, so harmonics of U20's 306 kHz switching are attenuated only by C49 and C50 before they reach the USB-C cable.

13.3.3 USB Boot Port J7 and USB-A Stack J8

AI-Assisted — J7 is the device-mode boot receptacle. All three Type-C checks are met. The shell is on its own bonded net, the GND contacts are on GND, and D14, D24 and D25 return to logic GND. CC1 and CC2 end only in the R33 and R34 Rd resistors, so nothing behind them needs a clamp.

U16 matters for D14 and D24. The FSUSB42 states its IEC 61000-4-2 figures only for the common D+ and D- pins, U16_3 and U16_4. J7 faces the HSD1 pins, U16_6 and U16_7, which carry only a component-level HBM rating.

USB_BOOT_VBUS is clamped by D25. It also drives two MOSFET gates, Q6 through R32 and Q1 through the J1 jumper.

J8 data lines have D26 to D29 in front of U9. U9 carries its own third-party IEC 61000-4-2 rating, so this path has two protection stages.

The J8 VBUS clamps D30 and D31 sit directly at the U11 and U12 switch outputs. The RT9742 has only a 2 kV HBM rating, which is a component-level figure and is a different quantity from a system-level IEC strike.

The J8 shell shares Net-(J7-SHIELD) with J7. Separately, the power review's note on the missing 120 µF port capacitance bears on hot-plug transients at these contacts.

13.3.4 HDMI J6

AI-Assisted — J6 is a right-angle SMD HDMI receptacle facing the outside of the product. Its shell is on Net-(J6-CKS), bonded to GND through C44 and R30, and J6_17 GND is on GND.

The TMDS pairs pass flow-through D12 and D13. HPD, SDA, SCL and CEC pass flow-through D15. All three arrays have both ground pins on logic GND, and their IEC 61000-4-2 and EFT ratings exceed the IEC 61000-6-2 levels. Each protected pin sees the array as the last clamp before it. The arrays clamp at 15 V maximum at 1 A (8/20 µs), and the CM4S datasheet gives no transient rating for its HDMI pins.

The J6_18 +5V contact carries HDMI_5V back to U14_1 VOUT, C43 and the DDC pull-ups with no clamp on that net. This is the only power contact on the external connectors with no clamp. U14's 2 kV HBM rating is a component-level figure, not comparable to an IEC 61000-4-2 strike.

The pair-shield contacts sharing the shell net, the DDC standoff and the HPD level are covered by the signal-integrity review.

HDMI TMDS clock and data run at up to 1.485 Gbit/s, which makes them the largest radiated-emission source on the board (CISPR 32). The 100 Ω pairs and the shell bond are the controls drawn.

13.3.5 Ethernet J4

AI-Assisted — J4 is an RJ45 magjack, rated 10/100 with Auto-MDIX, intended for external cabling. It has no datasheet in this review, so the following comes from connectivity alone. Its chassis contact J4_13 is the board's only Earth connection, and J4_8 is on GND.

LAN1_TXP, LAN1_TXN, LAN1_RXP and LAN1_RXN run straight from the magjack to U9_52 through U9_56. The only other parts on these nets are the 49.9 Ω terminations to VDD33A_LAN1, and there is no ESD array on them.

U9 states ±8 kV contact and ±15 kV air per IEC 61000-4-2. However, the magnetics' isolation and the PHY's own ESD structures do not cover differential-mode transients that pass the transformer, cable discharge events, or the IEC 61000-4-5 surge that IEC 61000-6-2 applies to signal cables longer than 30 m. A low-capacitance array on the PHY side of the magnetics, terminated to logic GND, is the conventional answer unless the magjack datasheet states integrated protection.

The link and speed LED cathodes J4_10 and J4_12 connect directly to U9_21 and U9_22. These LEDs sit at the panel face, so a discharge to the jack can couple onto those pins.

13.3.6 microSD J5 and Headers J1, J2

AI-Assisted — J5 is a card socket. It takes no cable from equipment at a different potential, so a direct bond of its shell contacts to logic GND is acceptable. Its six data clamps and the SD_PWR clamp are covered by the memory-bus and power reviews.

J1 is a vertical three-pin boot jumper used internally. USB_BOOT_VBUS on J1_1 is already clamped by D25.

J2 is a vertical 2×20 header and is internal unless the product cables it off the board. Its 26 GPIO lines land on the 5 V-side B ports of U3 to U5 and U6, and its +3V3 and +5V contacts have no clamp.

The TXS0108E B port has an IEC 61000-4-2 rating of 8 kV contact and 6 kV air. 6 kV air falls short of the 8 kV air level in IEC 61000-6-2. The TXB0108 carries only an HBM figure, which is a component-handling rating and not a system rating.

Whether J2 needs an array therefore depends on whether it leaves the enclosure.

13.3.7 Relay Terminal J3

AI-Assisted — J3 is a 45-degree 3.5 mm pluggable terminal carrying only the RELAY1_COM, RELAY1_NO and RELAY1_NC contacts of K1. These are outputs that K1 switches toward off-board equipment, so no input filtering applies.

No RC snubber or varistor is drawn across the contacts. With an inductive load, contact arcing at make and break produces broadband conducted and radiated emissions (CISPR 32).

The field cable also brings IEC 61000-4-4 burst and IEC 61000-4-5 surge to the contact set. That energy is kept from the logic only by K1's contact-to-coil insulation, which is not stated in the data supplied.

The switched voltage and load current are still open from the power review, and both decide the suppression part.

13.4 Observations

AI-Assisted — The board's transient protection is broad. Every external signal contact on J5 to J9 has a clamp referenced to logic GND, and the ESD9B5.0ST5G and RClamp0524PA ratings exceed both IEC 61000-6-2 and IEC 61000-4-2 level 4. The open items fall into four groups.

The first is coordination with the protected pins. Every clamp's 8/20 µs level is stated, but none of the protected ICs gives a transient rating for the same waveform. The rows therefore ask for that check rather than declaring a margin.

The second is shield-bond intent. J9's shell sits on logic GND, and J7 and J8 share one shield net. All bonds use 1 nF rather than 4.7 nF, and mounting holes H1 to H4 on GND can bypass the bonds in a metal enclosure.

The third is the three entry points with no clamp: the J4 Ethernet pairs on the PHY side of the magnetics, the J4 LED pins, and the J6_18 +5V contact.

The fourth is emission sources with no filtering at the cable: HDMI TMDS, U20 switching harmonics reaching J9, and relay contact arcing at J3.

None of these is a missing-protection defect. Each is a design choice that an industrial EMC test campaign will exercise.

13.5 Findings

#ConnectorFindingSeverity
13.5.1J9Shell contact J9_S1 shares the logic GND net, so the shield-bond strategy is not captured as design intent. Assign a dedicated SHIELD_GND_J9 net so the pour and bond parts are explicit. A copper pour under the connector, stitched directly to logic GND, is an acceptable simplification for a board that has no access to an earth ground and will not be ESD-tested. For professional designs, with or without earth ground access, use 1 MΩ || 4.7 nF (≥2 kV) from SHIELD_GND_J9 to logic GND. USB Type-C R2.5 section 3.2.1; IEC 61000-4-2.Medium
13.5.2H1, H2, H3, H4The board mounting holes are on GND. If they are fixed to an earthed metal chassis on conductive standoffs, they bond logic GND hard to chassis and bypass C40/R26, C44/R30 and C56/R54 as the defined ESD entry points. For a metal enclosure, consider isolating these holes or bonding them through a 1 MΩ || ≥2 kV capacitor network. IEC 61000-4-2.Review
13.5.3J4, J6, J7, J8 (C40, C44, C56)Each shield or chassis bond is 1 nF 2 kV with 1 MΩ. The 2 kV rating covers the strike. 1 nF, about 1.6 Ω at 100 MHz, is a weaker high-frequency bond than the 4.7 nF, about 0.3 Ω, of professional shield-bond practice. Consider 4.7 nF rated ≥2 kV where cable radiated-emission margin is tight. IEC 61000-4-2; CISPR 32.Review
13.5.4J9 (D16, D17)U19 CC1 and CC2 are rated 25 V so that a cable fault shorting CC to VBUS is survivable (Hynetek HUSB238 datasheet pp.7, 9, source: Tomachie). With D16 and D17 fitted, the CC lines instead tolerate only up to the 5.8-7.8 V breakdown (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). At the strapped 5 V contract, a 5.5 V maximum short is below V_BR(min) 5.8 V. If the port can ever carry a higher VBUS, a CC clamp whose breakdown exceeds that VBUS keeps U19's short tolerance.Review
13.5.5J9 (D16, D17, D19, D20)The clamps limit to 12.5 V maximum at 1 A and 15.0 V at 2 A (8/20 µs, 25 °C) (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). Check that U19_4 CC1, U19_5 CC2, U19_2 D+ and U19_3 D- are rated for this waveform. U19 states DC absolute maxima only (CC 25 V, D+/D- 12 V) and ±6 kV HBM (Hynetek HUSB238 datasheet p.7, source: Tomachie).Review
13.5.6J9The series elements between the J9 VBUS contacts and U20 are F1, Q7 and R45. None is a filter element, so harmonics of U20's 306 kHz switching are attenuated only by C49 and C50 before reaching the USB-C cable. Consider a ferrite or LC stage at the U20 input if DC-port conducted emissions are assessed. CISPR 32; IEC 61000-6-4.Review
13.5.7J7 (D14, D24)D14 and D24 clamp at 12.5 V maximum at 1 A (8/20 µs, 25 °C) (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). The FSUSB42 IEC 61000-4-2 figures (8 kV contact, 15 kV air, typical) are stated for U16_3 D+ and U16_4 D-. J7 faces U16_6 HSD1- and U16_7 HSD1+, which carry only the 8 kV HBM I/O-to-GND rating (Fairchild FSUSB42 datasheet p.3, Datasheet). Check that U16_6 and U16_7 are rated for this waveform.Review
13.5.8J7, J1 (D25)USB_BOOT_VBUS is clamped by D25 at 12.5 V maximum at 1 A (8/20 µs, 25 °C) (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). The net reaches the Q6 gate through R32 and the Q1 gate through J1 pins 1-2. The 2N7002W states VGS 20 V continuous and 40 V pulsed, with no waveform given (onsemi 2N7002W datasheet p.1, Datasheet). Check that the Q1 and Q6 gates are rated for this waveform.Review
13.5.9J8J8_S1 to J8_S4 share Net-(J7-SHIELD) with J7_SH, so both receptacles' pours and the C56/R54 bond form one net. A dedicated SHIELD_GND_J8 net with its own 1 MΩ || ≥2 kV capacitor keeps each strike entry at its own connector, which matters where J7 and J8 are not adjacent. IEC 61000-4-2.Review
13.5.10J8 (D30, D31)D30 and D31 clamp 5V_OTG_1 and 5V_OTG_2 at 12.5 V maximum at 1 A (8/20 µs, 25 °C), directly at U11_1 and U12_1 VOUT (onsemi ESD9B5.0S datasheet p.2, source: Tomachie). The RT9742 states 2 kV HBM, component level, and a 7 V VIN absolute maximum (Richtek RT9742 datasheet p.5, source: Tomachie). Check that U11 and U12 VOUT are rated for this waveform.Review
13.5.11J6 (D12, D13)D12 and D13 clamp at 15 V maximum at 1 A (8/20 µs, 25 °C) (Semtech RClamp0524PA datasheet p.3). Check that U2_111, U2_113, U2_117, U2_119, U2_123, U2_125, U2_129 and U2_131 (HDMI TMDS) are rated for this waveform.Review
13.5.12J6 (D15)D15 clamps HDMI0_CEC, HDMI0_SDA, HDMI0_SCL and HDMI0_HOTPLUG at 15 V maximum at 1 A (8/20 µs, 25 °C) (Semtech RClamp0524PA datasheet p.3). Check that U2_171, U2_173, U2_175 and the Q4 gate are rated for this waveform. The Q4 gate is rated VGS 20 V continuous and 40 V pulsed, with no waveform given (onsemi 2N7002W datasheet p.1).Review
13.5.13J6The J6_18 +5V contact has no transient clamp. HDMI_5V reaches U14_1 VOUT, C43 and the R5/R58 DDC pull-ups. Consider a 5 V-class TVS on HDMI_5V at J6, as fitted on the other VBUS-type contacts. IEC 61000-4-2.Review
13.5.14J4LAN1_TXP, LAN1_TXN, LAN1_RXP and LAN1_RXN run from J4 to U9_52 through U9_56 with only R36 and R55-R57 (49.9 Ω to VDD33A_LAN1), and no ESD array. U9 is rated ±8 kV contact and ±15 kV air per IEC 61000-4-2 (SMSC LAN9512 datasheet p.235, Datasheet). Magnetics and PHY ESD do not cover differential-mode transients, cable discharge, or the IEC 61000-4-5 surge that IEC 61000-6-2 applies to cables over 30 m. Investigate a low-capacitance array on the PHY side of the magnetics, terminated to logic GND, unless the magjack states integrated protection.Review
13.5.15J4J4_10 LEDG_K and J4_12 LEDY_K connect directly to U9_21 nLNKA and U9_22 nSPD with no clamp. The LEDs sit at the jack face, where a panel discharge couples onto them. U9 signal pins are rated +6 V / -0.5 V DC (SMSC LAN9512 datasheet p.235). Consider a clamp at U9_21 and U9_22 if panel ESD testing applies to the jack.Review
13.5.16J2J2 is a vertical 2×20 header, internal unless cabled off the board. Its 26 GPIO lines land on U3-U5 TXS0108E B ports, rated 8 kV contact / 6 kV air per IEC 61000-4-2 (TI TXS0108E-Q1 datasheet p.5, Datasheet). Two land on U6 TXB0108 B ports, which have only a ±15 kV HBM rating (TI TXB0108 datasheet p.5, Datasheet). The +3V3 and +5V contacts have no clamp. If J2 leaves the enclosure, 6 kV air is below the 8 kV air of IEC 61000-6-2, and an array at the header is warranted.Review
13.5.17J3J3 carries only K1 contacts RELAY1_COM, RELAY1_NO and RELAY1_NC, which are outputs toward off-board equipment, so no input filtering applies. No RC snubber or varistor is drawn across the contacts. With an inductive load, contact arcing produces broadband emissions (CISPR 32). The field cable brings IEC 61000-4-4 burst and IEC 61000-4-5 surge to the contacts, and K1's contact-to-coil insulation is the only barrier to the logic. Size suppression to the switched load once its voltage is stated.Review
13.5.18Earth / GND (C40, R26)Earth and GND are joined by C40, 1 nF rated 2 kV, in parallel with R26, 1 MΩ. This is a deliberate high-impedance chassis bond. J4_13 CHASSIS is directly on Earth. IEC 61000-4-2.✓
13.5.19J9J9 GND contacts A1, A12, B1 and B12 are hard on logic GND. D16, D17, D19 and D20 return to logic GND, not a shield net. The symbol has no mid-plate pin. USB Type-C R2.5 section 3.2.1.✓
13.5.20J5, J7, J8, J9 (ESD9B5.0ST5G)Rated ±18 kV contact and air per IEC 61000-4-2, and 40 A EFT per IEC 61000-4-4 (onsemi ESD9B5.0S datasheet p.1, source: Tomachie). This exceeds the 4 kV contact / 8 kV air of IEC 61000-6-2 and level 4 (8 kV / 15 kV). Ratings are at 25 °C; the design states no maximum ambient.✓
13.5.21J7J7_SH SHIELD is on Net-(J7-SHIELD), bonded to GND through C56, 1 nF 2 kV, in parallel with R54, 1 MΩ. The J7 GND contacts are on GND, and D14, D24 and D25 return to logic GND, so all three Type-C shield checks are met. USB Type-C R2.5 section 3.2.1; IEC 61000-4-2.✓
13.5.22J7J7_A5 CC1 and J7_B5 CC2 reach only R33 and R34 (5.1 kΩ to GND). No active pin sits behind them, so these contacts need no clamp.✓
13.5.23J8 (D26, D27, D28, D29)The USB_OTG_1 and USB_OTG_2 lines have ±18 kV clamps (onsemi ESD9B5.0S datasheet p.1, source: Tomachie) ahead of U9_1 to U9_4. U9 is itself rated ±8 kV contact and ±15 kV air per IEC 61000-4-2, third-party tested (SMSC LAN9512 datasheet p.235, Datasheet). Both stages meet level 4.✓
13.5.24J6J6_SH is on Net-(J6-CKS), bonded to GND through C44, 1 nF 2 kV, in parallel with R30, 1 MΩ. J6_17 GND is on GND. IEC 61000-4-2.✓
13.5.25J6 (D12, D13, D15)D12 and D13 (TMDS) and D15 (HPD, SDA, SCL, CEC) are wired flow-through, with both ground pins on logic GND. They are rated ±12 kV contact and ±17 kV air per IEC 61000-4-2, and 40 A EFT per IEC 61000-4-4. This exceeds IEC 61000-6-2 (Semtech RClamp0524PA datasheet pp.1, 3, Datasheet).✓
13.5.26J5J5_S1 to J5_S4 are directly on GND. A card socket takes no cable from equipment at a different potential, so a direct bond to logic GND is acceptable. All six SD lines and SD_PWR have clamps (D9, D10, D32-D35, D11).✓
13.5.27J1J1 is a vertical three-pin boot jumper used internally. J1_1 USB_BOOT_VBUS is already clamped by D25, and J1_2 reaches only the Q1 gate and R1 (47 kΩ to GND). No further protection is needed.✓

14.8 Boundary Scan Testability

Boundary scan capable device(s) were identified, but no JTAG test access exists - the TAP pins are not reachable from any connector, test point, or probe point.

14.8.1 Boundary Scan Capable, TAP Not Accessible

U9 (LAN9512I-JZX) is boundary scan capable - BSDL LAN9512_JZX identifies the device - but its JTAG TAP pins have no test access. This is less than optimal for manufacturing test: route the TAP to a debug connector, or at minimum place test points on the TAP nets so test equipment can drive the boundary scan chain.

14.11 PCOLA/SOQ Testability

PCOLA/SOQ scores how well the configured test methods cover each component and each connection. PCOLA evaluates five device-level properties: Presence, Correctness, Orientation, Live (functional), and Alignment. SOQ evaluates three connection-level properties: Shorts detection, Opens detection, and solder joint Quality. Scores are on a 0–100,000 scale where 100,000 means every property is fully covered. The Combined score is the average of PCOLA and SOQ.

14.11.1 Coverage by Test Method

P=Presence C=Correctness O=Orientation L=Live A=Alignment | S=Shorts O(pins)=Opens Q=Quality

PCOLA/SOQ coverage scores by test method. Scores: 0 (None), 0.5 (Partial), 1.0 (Full).

15 Component Properties

Schematic library symbol quality analysis.

The datasheet link stored in the schematic was followed, and the document it returned was compared against the part number. The rows below are links that resolved to a document covering a different part - most often a sibling variant of the same family, where the specifications read as plausible but describe the wrong device.

15.2 Library Symbol Grades

Grading schematic library symbol quality based on pin electrical type definitions:

Grade Definitions
GradeRatingDescription

15.3.1 Validation Heuristics

All pins same type: Generic library with no electrical rules

High % passive pins on IC: Incomplete type information

No power pins: May indicate separate power symbol

Low type diversity: Very underspecified library symbol

Power-named pins not typed as Power: Library pin types incomplete

15.4 Symbol vs Datasheet Pin Table

Each symbol's pin numbers are compared with the pin table of its datasheet. A datasheet pin the symbol lacks is a warning only when the datasheet calls it electrical; a pin the datasheet marks NC or mechanical, or a symbol pin the table does not list, is shown for information. An exposed pad is never counted as a mismatch, whether the symbol names it or numbers it one past the last pin. Where it was numbered, the row suggests giving it a name, because a bare number does not tell a reader what the pin is.

117 parts compared with their datasheet: 114 agree, 3 differ.
