LMK05028: 1PPS Sync

Part Number: LMK05028
Other Parts Discussed in Thread: LMK05318

Hello,

My goal is to create synchronized Low jitter clocks on 2 (or more) different cards (inside each cards and among all cards), using a splitted 1PPS signal from external source.

I also need to use the same 1PPS to sample it later using one of these clocks. I'm looking for the best way to accomplish it.

I saw the LMK05028 device (also the LMK05318), which seems to be capable of synchronizing with 1PPS.

The questions are:

Which device is better to use an how,  and what is the maximum skew I shell get between the the clocks in a single card, and among different cards?

(Among different cars, the requirement is up to few nsec)

Thanks!
