Hello,
What is the PCLK frequency of the 921 - 940 link?
Have you tested the internal pattern generation mode and the BIST mode to verify PAS functionality and test the validity of the 921-940 link?

please check and feedback:

1. data pattern test is correct or not?

2. the real case resolution?

3. what is the DE signal in UB921 side?

regards,

Steven
