DS90UB954-Q1: The current product has encountered EMC problems

Part Number: DS90UB954-Q1

The current product has encountered EMC problems, and we plan to reduce the frequency point energy through the frequency spread function of DS90UB954-Q1.

But the description in the datasheet is not exhaustive. What registers need to be configured to implement the frequency spread function of SERdes, or do you have a specific instruction manual?

I look forward to your reply. Thank you!

    Hello Bao,

    The SSC is not generated internally on this device. To use SSC, you must provide a REFCLK to the part externally which has SSC within the bounds of the datasheet above and the serializer must be in synchronous mode. If that is done then the FC and BC signals will then have SSC applied. There is no register configuration needed

    Best Regards,
