PeriodJitter
As data rates increase, effects of jitter become critical with
itsbudgetstighter. Jitteristhedeviationofatimingeventof
a signal from its ideal position. Jitter is complex and is
composed of both random and deterministic jitter
components. Randomjitter(RJ)istheoreticallyunbounded
and Gaussian in distribution. Deterministic jitter (DJ) is
bounded and does not follow any predictable distribution.
DJ is also referred to as systematic jitter. A technique to
