ABSTRACT:
A slice level reference generator and method for performing improved data slicing operations when gaps are present in a data stream is disclosed that involves applying a nominal reference signal to the comparator the during signal gaps. In one embodiment, a receiver circuit includes a slice level detector and a comparator that operate in a conventional manner, and control circuitry that utilizes a signal detector and a switch to store a slice level reference signal generated by the slice level detector during a first signal burst, and to apply the stored reference signal to the comparator during signal gaps. In one embodiment a timer circuit is used to detect signal gaps. In another embodiment a predetermined fixed reference signal is applied to the comparator during signal gaps.
