we have designed a pll,with nearly 4ps RMS jitter with OSC measured. but with the Spectrum Analyzer ,the phase noise has the different value in the different frequency point ./ [+ h4 E2 S9 K3 c! r [
we want to know the different of the RMS jitter and phase noise: RMS jitter ,only a value ,but the phase noise has the different value in the different frequency point . why ? 0 C- Y" `5 }7 A* v% wthank you
I know the define of the rms jitter and phase noise ,9 S$ r* }! g7 F' s; c
but I want to know the relation of the rms jitter and phase noise. M. O+ n. X8 v) {( |% sone of paper said the rms jitter is the integral of the phase noise, but from which offset frequency?. A9 _0 v1 h" ~ `. ^
and according to the test result, this relation is no true. why ? ! t: [* u& E3 M! M, hthank you !
