DS90UB953-Q1: What kind of data will pass through from 953

Part Number: DS90UB953-Q1

Hi,

 

While 953/954 work in idle mode, what kind of data will pass out from 953 to 954 through FPDLink and 954 to system through CSI2? Is there different with normal operation?

Because system receive date even though without camera.

 

Thank you.

    Hi,

    When CSI2 input data of UB953 is less than the FPD-Link throughput rate, the idle will be sent out in the FPD-Link. For the CSI2 output I/f of UB954, the line/frame blanking will be inserted and the CSI2 data lane is translated from high speed to low power status LP11, which is shown in d/s.

    best regards,

    Steven
