Hey Nathan,
If it is just due to thermal issues, I suspect it stems either from the quantity of copper the PowerPad is connected to, and/or insufficient solder to the pad:
1. Quantity of copper: See this image from Best Practices for Board Layout of Motor…
Hi Alvaro, Sorry for late reply, Kindly find requested items. 8130.PHY_Interface.pdf Link for Checklist access: 2744.DP83822_Schematic_Design_Review_Checklist.xlsx
Thanks..
Hi Kavin,
I want to thank you again for providing the filled out checklist, as well as the schematic pdfs. This made the review very easy. Please find my comments in the attached document under the Pin Wise Checklist Tab.

Hi Mike,
For schematic and layout designs, TI Ethernet has crafted a checklist for customers to utilize to expedite schematic reviews due to their familiarity with the design. However, if any questions were to arise from the initial checklist, we can…
Hi Cedrick
LT1004 and LM336 are shunt references (Similar to Zener diode ). You need to force a minimum current for a regulation.
A voltage source with a series resistor full fill that requirement. You can tune your resistor value based the the supply…
Hi Patrick,
The probe connected in my setup is a TDP1500 - it has 200K differential input resistance, is that fine? https://www.tek.com/en/datasheet/differential-probes
sensor min freq 8/3 = 2.67MHz seems a better fit for our device which operates at…
Part Number: DP83867IR Other Parts Discussed in Thread: TXU0104
Hi, My customer is designing their board with Sitara AM62x and DP83867IR. In their schematics, PHY nRESET_N signal is driven by AM62x PORz_OUT signal with TXU0104 (3.3V to 1.8V level shifter…
Hi Sir,
I apologize for getting back to you late.
Please help review the below checklist and advise some comments.
Another question is the pull/down resistor value on the H/W configuration, is there use the 2.49kOhm(refer to the EVM schematics) or 10kOhm…
