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.

A method for the recovery of a clock signal from a data signal, wherein edges of the signals are each represented as a chronologically-ordered sequence of timing points, said method comprising, in one procedural stage, a plurality of timing points of the data signal is processed in parallel as follows:
- resolving the timing points of the data signal by a nominal clock pulse;
- estimating bit-period deviations for the adjusted timing points;
- and
- injecting the nominal clock pulse to the estimated bit-period deviations.
A device for recovery of a clock signal from a data signal, wherein the signals are each represented as chronologically-ordered sequences of timing points, said device comprising:
- means for resolving the timing points by a nominal clock pulse;
- means for estimating bit-period deviations for the adjusted timing points;
- and
- means injecting the nominal clock pulse to the estimated bit-period deviations,
- wherein the means for resolving, the means for estimating, and the means for injecting are arranged and connected to one another in such a manner that, in one procedural stage, a plurality of timing points of the data signal can be processed in parallel.
