Sequential synchronizers with the pulse comparation and clock sampling variants

Abstract

The function of the synchronizer is to sample the data with the minimum bit error rate (BER) and to retime its bit duration with the original format. In this work, we present the sequential synchronizer with two variants which are the pulse comparation discovered by Hogge and the clock sampling discovered by us. Each variant has two versions which are the manual and the automatic. The main objective is to study, in the four synchronizers, the output jitter as function of the input signal-to-noise ratio.
