DS90UB926Q-Q1: DS90UB926 B0,B1,G0,G1 no output

Part Number: DS90UB926Q-Q1

We are developing an application for a video link serializer and deserializer for vehicles.

We are using the DS90UB926 deserializer with the DS90UB929 serializer.

However, during the hardware testing process, we found that the B0-B1 G0-G1 four signals have no output remaining at 0.

But when we configure the DS90UB926 to output a test pattern, the B0, B1, and G0, G1 signals have output.

Could you please provide some guidance and solutions on how to troubleshoot this issue? Thank you for your assistance.
