Understanding and characterizing timing jitter
Matthew Zaleski found this resource posted by National Instruments. It’s a fairly detailed whitepaper titled “Understanding and Characterizing Timing Jitter”. This looks like a good resource for anyone doing high-frequency communications.

Nice find Matthew. The app note publish is dated is 23 January 2013. There is a .pdf download on the page linked in the original post.
However, there is really nothing in this application note that deals with Jitter vs. Phase Noise – which are equipollent (but not equivalent). – A deep subject. But one anyone dealing with timing and communications systems should understand the difference.
Also, the document doesn’t really explain how jitter/phase-noise is affected by N times multiplication (worse) or division (better) – theoretically 20*log(N). A proper treatment of the multiply/divide factor should also include how non-ideal (and non-linear) devices doing the multiplication or division can add to the noise themselves. Again – a deep subject.
But he NI note is worth a download IMO… Thanks
