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 .: k# t) H& [! m( {' p9 N3 ~+ P% F: l
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 ? O" p5 _2 a1 {: l6 `& B+ e% Tthank you
I know the define of the rms jitter and phase noise ,7 V' }! j$ H9 b* i# T9 ^
but I want to know the relation of the rms jitter and phase noise. 5 a- d, X8 ^* @' G! {3 J
one of paper said the rms jitter is the integral of the phase noise, but from which offset frequency? ; v, L7 H" t, Z r4 G; Rand according to the test result, this relation is no true. why ? & H$ k6 j; j: V, h( C5 mthank you !
