Jitter is the deviation from true periodicity of a presumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals.Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48).bsolute jitter is the absolute difference in the position of a clock's edge from where it would ideally be. Period jitter (aka cycle jitter) is the difference between any one clock period and the ideal/average clock period.
