I have rms jitter specification for a pll. what actually this refers to?
Is this random jitter?
If we do the phase noise simulation and calculate jitter value, what jitter we get?
 

Since random jitter is unbounded, rms is the effective way to represent it. If you want the random jitter in pk-pk term, you need to use a scaling factor for a specified BER. Otherwise, you cannot get the pk-pk value out of rms.

If you got the phase noise, saying N, then your rms jitter in radian is sqrt(10^(N/10))*2. Thus, rms jitter in second is jitter_in_radian/(2*pi*frequency)

Click to expand...

rms jitter is the algrithmic, you can calculate the rms jitter of cycle jitter, periold jitter and so on.
