C10G SOM – Thermal Analysis and Power Dissipation¶
This document outlines the power consumption and thermal performance of the C10G SOM under various heatsink and fan configurations. All tests were run using the devkit reference design available here:
Critical Link MitySOM-C10G Reference Project – pro_24.1_stable
- Processor Clock: 100 MHz
- Transceiver Reference Clock: 100 MHz
- Temperature readings obtained using the
tempvoltconsole command - Ambient temperature held at 20 °C
Thermal Results – With Transceivers Enabled¶
| Heatsink | Does Heatsink include a Fan? | External Fan | Ambient (°C) | Device (°C) | ΔT (°C) | Power (W) |
|---|---|---|---|---|---|---|
| None | No | Yes | 20 | 52.4 | 32.4 | 6.84 |
| ATS-52290G-C1-R0 | No | No | 20 | 82.85 | 62.85 | 8.16 |
| ATS-52290G-C1-R0 | No | Yes | 20 | 42.25 | 22.25 | 6.60 |
| ATS-61290W-C2-R0 * | Yes | No | 20 | 42.92 | 22.92 | 6.60 |
Thermal Results – With Transceivers Removed from FPGA Design¶
| Heatsink | Does Heatsink include a Fan? | External Fan | Ambient (°C) | Device (°C) | ΔT (°C) | Power (W) |
|---|---|---|---|---|---|---|
| None | No | Yes | 20 | 44.28 | 24.28 | 3.84 |
| ATS-52290G-C1-R0 | No | No | 20 | 59.84 | 39.84 | 4.20 |
| ATS-52290G-C1-R0 | No | Yes | 20 | 37.51 | 17.51 | 3.72 |
| ATS-61290W-C2-R0 * | Yes | No | 20 | 38.86 | 18.86 | 3.72 |
Notes¶
- ATS-61290W-C2-R0: The MAXIGRIP clip does not attach properly to the SoC due to clearance issues. The fan was attached directly using thermal tape.
- External fans used were Sanyo Denki 9G1224G101.
- Temperature rise is calculated as ΔT = Device Temp − Ambient Temp.
