I've a simple question regarding CY22150, to which I wasn't able to find a solution in datasheets, forum nor knowledge-base.
In our design, we want to minimize the period jitter of CY22150's outputs to a minimum. I've found that we have to raise VCO frequencies, but can you tell me if it is (in terms of jitter performance) better to use
- an external, low-jitter clock as a reference
- or a crystal input
- or no difference between both options?
Are there other things or settings we have to take into account to minimize the output jitter?
Thanks a lot,
