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

Hi,

   

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
