DS280DF810: Can I use a retimer to synchronize to a clock?

Bonf

Part Number: DS280DF810

I need to retime 4 data lanes (12.5Gbps) to a clock(12.5GHz). My solution would be to feed the data and the clock through the DS280DF810 retimer.

Is there any way to make the clock the "master" signal that the others should align to?

Can one change the importance of one lane relative to others?

I need the data to align with a rising clock, is there a way to ensure that it align with the rise but not the fall?

The clock will be moved during calibration and I need all the data lanes to move too.

Thanks,

Marc.

    Hi Marc,

    The DS280DF810 retimer implements a reference-less CDR, meaning that it recovers the clock from the input data and then uses it to output a retimed version of it. Additionally, each retimer channel is independent. Thus, I don't think that the DS280DF810 may be used for data lanes synchronization to some reference clock as you are requesting
