DS90UB953-Q1: CSI_ERR_CNT between Serializer and Deserializer

RoyChen776

Part Number: DS90UB953-Q1

Hello,

Our clients tell us of a problem, they cannot grab images after initializing our camera.

They checked the ERR_CNT register,

It is always ZERO on the Serializer/953 side, but it continues increment on the Deserializer/954 side.

And the lock signal is unstable.

Also, they use the pattern-gen on the Serializer. Everything works fine.

I think pattern-Gen can check the link health, but why the deserializer has ERR_CNT occurred when using the sensor's CSI data?

Thanks!

Hello Roy,

Have you checked the PoC filter is as per our recommendation?

Have you tested with different cable length/ cable type if possible?

Can you please provide more details about the system, such as:

Clocking Mode

Input Data Parameters (V & H resolution, FR, Data Type, Blanking)

Pattern generator Data Parameters (same as above)

Number of CSI-lanes used on the SER
