Abstract
The present invention relates to a method for recovering a clock from a run-length-coded data stream, said method making it possible for a phase-locked loop to lock in a rapid manner, and also to a circuit for implementing the method. An inventive method for recovering a clock from a run-length-coded data stream comprises the steps of: ascertaining the distribution of symbol lengths in the data stream for a chosen clock period; determining the deviation of the maxima of the distribution of symbol lengths from integer multiples of the chosen clock period; and regulating the chosen clock period on the basis of the deviation determined.
