I have a 16GHZ pll and div by N is 160. I am trying to calculate random jitter from phase noise of VCO. I TRIED IN CADENCE by setting noise source type as jitter and then selecting FM jitter or PM jitter. I was wondering how to plot jitter information using above choices I have made in direct plot form.
Also, while calculating Random jitter the center frequency should be 100MHZ (crystal oscillation frequency) or 16ghz pll output frequency. what is the fc to calculate random jitter from phase noise of VCO
Please advise.
regards
