Clock recovery method and apparatus |
| 摘要 |
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. |

1. 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; and modifying a timing function value that corresponds to an estimated timing difference relative to the sampling clock signal, based on a change of the phase offset value, resulting in the timing estimation value, wherein the timing function corresponds to a Mueller-Müller timing function. |
