Jitter analysis of a double modulated threshold pulse stuffing synchronizer

A pulse stuffing technique (used for TDM) in which both positive and negative stuffings are allowed with two stuffing thresholds periodically modulated by a sawtooth waveform is discussed. A suitable mathematical model of the technique and a frequency domain analysis of the inherent pulse stuffing jitter are provided. It is found that the approach reduces the peak-to-peak pulse stuffing jitter according to the inverse of the threshold modulation period. The analytical results are confirmed by numerical simulations.<
