1. A method for reducing the jitter and wander of a data signal that is passed through a pulse stuffing synchronizer and desynchronizer, said method comprising the steps of:

  • (a) sequentially adjusting the phase of a reference clock signal so as to cause said reference clock signal to closely track the phase of a clock signal recovered from said data signal;

    (b) storing information representative of the net effect of phase adjustments of said reference clock in step (a);

    (c) conveying said net effect representative information stored in step (b) to said desynchronizer;

    (d) generating a sequence of phase adjustments in accordance with said net effect information; and

    (e) generating a clock signal for controlling the operation of said desynchronizer in accordance with said sequence of phase adjustments generated in step (d).
