Tolerance to Jitter and Wander (http://m2vtelecom.blogspot.com/2010/01/tolerance-to-jitter-and-wander.html)
A phase (http://en.wikipedia.org/wiki/Phase_%28waves%29) fluctuation of a signal (http://en.wikipedia.org/wiki/Signal_%28electronics%29) is an oscillating movement with an amplitude (http://en.wikipedia.org/wiki/Amplitude) and a frequency.
Strictly speaking, wander (http://en.wikipedia.org/wiki/Wander) is defined as the phase error comprised in the frequency band between 0 and 10 Hz of the spectrum of the phase variation. If this frequency is higher than 10 Hz, it is known as jitter (http://en.wikipedia.org/wiki/Jitter).
Jitter and wander affect every stage of data recovery, producing a number of sampling errors, clock, losses, and overflow.
