    摘要: The invention relates to a device for extracting a clock signal and digital data from a baseband serial signal, including a circuit (19) for sampling the signal received and a clock extraction circuit (12) comprising: an injection-locked oscillator (19), a phase-lock loop (25) and a phase pulse generator circuit (30) that delivers a pulse signal at the frequency of the received signal fronts with a pulse amplitude and duration adapted to the operating characteristics of the phase-lock loop (25). According to the invention, at least one phase shifter circuit (37) introduces a constant pre-determined phase shift to ensure phase alignment of the inputs (17, 18) of the sampling circuit (15).
