The importance of the jitter of a PLL

[AdvaRes]

Hi members,
Is it important/necesary/not neccesary to mention noise/jitter performance of a PLL if the oscillator will be used as a global clock for a digital circuit ?
Note that the PLL jitter is too small to affect to affect the functioning of all the logics forming the digital circuit in particular flip flops.

I'm writing my dissertation and I dont see a need to do that coz, AFAIK phase noise analysis for jitter calculation is done for PLLs dedicated to receivers and tranceivers (each endowed with the same PLL).

Am I right or wrong ?

Re: PLL and Jitter

It is possible for PLL jitter to cause timing issues. You may be correct in your statement that it doesn't in your case, but I think you should do enough analysis to back up that statement.
