A timing-phase recovery circuit, which is suitably mounted on a digital LSI, includes a timing phase recovery circuit. The timing-phase recovery circuit includes a first circuit for extracting a digital timing signal from a received input analogue signal, a second circuit for detecting a virtual zero crossing included in the digital timing signal in synchronism with a sampling signal and a third circuit for carrying out a phase shift with respect to the sampling signal in order to tune the timing signal to the frequency of the virtual zero crossings in a very short period of time.
