Hi Franco,

No percentage here, but useful insight anyway. I hope it will help you:

Dcs clock jitter specs

So, the accuracy needs to be higher than +/- 0.1 parts per million over time. Jitter (and subsequently phase noise) on a reference clock going into the Vivaldi Clock is largely irrelevant as in essence the Vivaldi Clock doesn’t respond to fast changes on the reference input - it has a slow ac…
