Clock recovery method, corresponding circuit and system

An input signal arranged in frames is received. The frames include a cyclic redundancy check (CRC) field including a number of bits having bit edges. A timing signal is generated to include adjustable duration waveforms at one of a first duration value and a second duration value. A CRC check determines the occurrence, over the duration, of a number of waveforms of the timing signal having their duration adjusted to one of the first duration value and the second duration value which corresponds to the number of bits. A check signal is produced having a pass/fail value. If pass, the duration of the waveforms in the timing signal is maintained adjusted to the one of the first duration value and the second duration value. If fail, the duration of the waveforms in the timing signal is re-adjusted to the other of the first duration value and the second duration value.
