Analysis of Jitter in a Digital Transmission System.
Abstract
This work outlines a method for predicting the accumulation of timing jitter in a digital transmission system. Earlier works have concentrated on regenerative repeators or pulse-stuffing multiplexer/demultiplexers, as the sole source of jitter, without regard to the digital transmission system as a whole. Here, the timing jitter accumulation is evaluated from source to sink with almost any sequence of repeater chains, multiplexers, switches and demultiplexers in between. The basic model for the jitter accumulation are taken from earlier works, such as the 1963 paper by Bryne et al, Systematic Jitter in a Chain of Digital Repeaters and the 1972 paper by Duttweiller, Waiting Time Jitter. These models have been reworked to some degree to reflect more recent timing extraction circuitry, but are basically unchanged from their original derivations. The digital transmission system is treated as a series of jitter transfer and jitter generation components which can be analyzed sequentially. The jitter is assumed to be an additive, random process whose spectrum is peak-to-peak, unit intervals versus frequency.
