Abstract

A method for the recovery of a clock signal from a data signal is provided where the edges of the signals are each represented as a chronologically-ordered sequence of timing points. In one procedural stage, a plurality of timing points of the data signal are processed in parallel as follows: resolving the timing points of the data signal by a nominal clock pulse; estimating the bit-period deviations for the adjusted timing points; and injecting the nominal clock pulse to the estimated bit-period deviations.
