DS90UB940-Q1: Power up sequence requirement

Part Number: DS90UB940-Q1

Hello Team,

As the power up sequence timing diagram, PDB need to be high after FPD data comes into DES

After PDB high, can customer configure DES configuration first before valid video comes into DES?? They will also implement soft reset after receive valid video. If so, they can save initialization time.

Thank you.

  • Hi Harry,

    As described below that table, if valid video is not being sent when 940 is powered up, it will require a soft reset. So you can configure the DES before, the after SER initialization is complete, run a soft reset.

    Best regards,
