SYNCHRONIZATION METHOD AND DEVICE REALIZING SAID METHOD

摘要

The synchronization method realizes synchronization of a digital input data signal with a digital clock signal with which the data signal is rate synchronous. The method consists in sampling the input signal, grouping these samples in successive sets of a plurality of successive ones of said samples, detecting in each of said sets possible value transitions of said samples, determining for each current transition in a set the theoretical position thereof in a corresponding set assumed to be obtained by sampling a nominal data signal which is the input data signal but with pulses having a width equal to the width of the clock signal period, and in using the latter theoretical position and the end value of the transition to generate the synchronized input data signal.
