Hi everybody,

I'm simulating the jitter of a low frequency crystal oscillator (32KHz) with pnoise analysis. I have read in many post that the stop frequency sweep range has to be set to half of the fundamental frequency (relative to the fundamental) to compute the jitter(in this case 16KHz).
Why? Is there any mathematical reason for that?
That means that the circuit noise contribute at frequency greather than f0/2 are not relevant for the jitter?

Thanks for your help.
