DS90UB948-Q1: Video signal detect

Ryan Wang

Part Number: DS90UB948-Q1

Dear expert,

Which register can indicate active video signal through FPDlink detected by UB948?

Is bit 1 "SIGNAL_DETECT" of 0x1C for this purpose?

Thanks

Hamzeh,

I tried this bit. However, it seems related with FPDlink signal present but not video signal.

Is there any other register available for video signal present?

Thanks

Okay sorry, I miss understood you.

Please monitor the LOCK bit in Reg 0x1C[0]. But before that you need to make sure reg 0x34[6] is at default means 0
