Jitter decomposition by time lag correlation

Jitter decomposition is important for accurately deriving the bit-error-rate in a system and for aiding in identifying the root causes of jitter. Limits of conventional solutions to this problem are discussed and a new approach to overcome the limitations is proposed. Our method uses time lag correlation functions to decompose different jitter components. The approach is validated by hardware measurements by applying the techniques to a phase locked loop into which jitter is injected
