ISSUE: The LP5912-1.8DRVT U60 on the common processor board is rated at 500 mA. It is used to drive the analog 1.8-V inputs to the AM6548. Initial testing has shown that this supply is underrated in some use cases.
SOLUTION: Customers should include a second 500-mA LDO specifically for the VDDA_1P8_SERDES0 power input on pins AA14, AB13, and AB15. This resolves the issue with U60.
