  • Patent number: 5276715
    Abstract: A method for reducing the phase noise introduced in the resynchronization of digital signals using positive, negative or positive-negative justification, in which a phase comparison signal representing the phase difference between signals from a local clock and a remote clock is generated, the comparison signal is modified by a suitable scale factor, the scaled phase comparison signal is integrated at a suitable frequency, the integrated signal is quantized by comparing the integrated signal with predetermined thresholds, and the transitions of the quantized signal are used to determine the justification events which are to be overlapped to a local unjustified clock rate to generate a local justified clock signal.
