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 .( M5 E1 L/ r0 z) ~9 }6 _
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 ?* {1 H0 U' V) u8 [
thank you
I know the define of the rms jitter and phase noise ,1 T4 ], ]% r8 N1 f* D
but I want to know the relation of the rms jitter and phase noise. 2 O/ p3 X# T& j$ [& O+ none of paper said the rms jitter is the integral of the phase noise, but from which offset frequency?: |; s7 d7 m4 a3 j5 ]6 c5 s# f
and according to the test result, this relation is no true. why ? , y, i3 I/ D; ?, ^- R5 y7 Rthank you !
