Abstract
Embodiments of this application provide a clock phase recovery apparatus and method, and a chip. The clock phase recovery apparatus includes an ADC, a dispersion compensation unit, a digital interpolator, a MIMO equalization unit, and a clock offset phase obtaining unit. The ADC is connected to the dispersion compensation unit, and the dispersion compensation unit is connected to a first input end of the digital interpolator. An output end of the digital interpolator is connected to an input end of the MIMO equalization unit, and an output end of the MIMO equalization unit is connected to an input end of the clock offset phase obtaining unit. The digital interpolator is configured to adjust, based on first offset phase information output by the clock offset phase obtaining unit, a dispersion-compensated signal output by the dispersion compensation unit.
