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 . 2 {/ {9 l+ v2 k, Lwe 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 ? % t3 w l5 g3 v' u- ]5 Bthank you
I know the define of the rms jitter and phase noise ,' O; E' ?4 z$ k" K4 X4 F8 Q" n
but I want to know the relation of the rms jitter and phase noise. " l5 b1 L, u U* J" d
one of paper said the rms jitter is the integral of the phase noise, but from which offset frequency?, w- w' m- y: c, P
and according to the test result, this relation is no true. why ? / R* y# L9 t4 @6 o2 \: zthank you !
