Hi,

As these are system level tests, I suggest taking a look at the implementation of the CSI-2 traces.

Below are layout guidelines for CSI-2 available in the UB960 datasheet:

Secondly, we recommend checking the VDD18 rails on the UB960 to confirm the rails are within specification of VDD18 with voltage 1.8V +/-10% and no more than 25mVpp noise.

Best,

Zoe
