DS90UB913A-Q1: PCLK Detect Criteria

Part Number: DS90UB913A-Q1

Hey Team,

Could you share details of what criteria the 913 looks for to flip the PCLK Detect bit to 1:

I have a troubleshooting situation where we are getting 0x13 for register 0x0C so we are getting a lock but no PCLK so wanted to confirm what is required to have a "valid PCLK"

Thanks!

David

    David,

    I believe the condition of LOCK = 1 but valid PCLK = 0 will occur if the link is running on 913A AON clock. So I think you would want to verify that the serializer has a valid input clock either from external oscillator or directly from the imager PCLK input depending on the SER operating mode

    Best Regards,

    Casey
