How to debug the adc data

Hi

I use the ADRV9029 device on our custom board.
The FPGA sometimes receive incorrect ADC data. (around 10%)

In some cases, only the rx1 data is incorrect.
In other cases, the rx1 and rx2 data are incorrect.

On the FPGA side, deframer status is correct.

After the ADRV9029 is reset and re-configure, all the data is correct therefore I assume the ADRV9029's data incorrect.

Please refer to setting file.
2781.initdata.txt


I want to know how to debug this issue.
