Random and deterministic jitter

摘要

Many Clock-Recovery Circuits produce a repetitive, predictable jitter. This effect is particularly noticeable in cheesy clock-multiplier circuits and poorly equalized data-recovery units. The name for the predictable component of jitter in these circuits is deterministic jitter. The remaining components of jitter constitute random jitter. You can usually presume that deterministic- and random-jitter components are not correlated.
