    CY22150: external clock vs. crystal input in terms of jitter



      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,


      bye, Harald
