Abstract
The invention relates to a phase rotation method for a clock recovery, comprising the steps of: providing a timing estimation value that indicates for each input data symbol at least whether an input data sample has been sampled early or late by a sampling clock signal; generating a phase offset value indicating a phase rotation of the sampling clock signal based on the timing estimation value; modifying the timing function value based on a change of the phase offset value, resulting in the timing estimation value.
