Part Number: DS90UH981-Q1

Tool/software:

When using the DS90UH981 serial port, should the upstream module (DSI TX) of DS90UH981 be configured first, or should DS90UH981 be configured first? Is there a recommended power on process?

    Hello,

    981 has a video possessor which requires active video input in order to establishes synchronization, so DSI video source should be configured first and active video should be outputted then SERDES config after. Please follow datasheet recommendation for power-up sequence.
