Hello,
As for the TI's 16ch re-timer DS125DF1610FB, I use 10G Ethernet (10.3125Gbps).
How long is the CDR unlock time when there is no data input?
And how long is the CDR lock time after data is input?
thanks,
TS

The unlock time is very fast, as it is triggered by the signal detect circuit being de-asserted. It will be in the order of hundreds of microseconds.
The DS125DF1610 CDR lock acquision spec per datasheet is within 100 milliseconds.

CDR lock time, though characterized, is not listed on the datasheet. For default settings CDR lock time will not exceed 100ms.
