Abstract
Disclosed are a clock and data recovery circuit, method and apparatus. The circuit comprises a receiving module for receiving an analog signal; a first equalization module connected to the receiving module, the first equalization module comprising a first totalizer and a second totalizer; a first sampling module connected to an output end of the first totalizer, the first sampling module comprising a first edge sampler and a second edge sampler that are connected to the output end of the first totalizer, respectively; a second sampling module connected to an output end of the second totalizer; a data processing module connected to both the first sampling module and the second sampling module; a clock recovery module connected to the data processing module; and an output module connected to the clock recovery module. In the present application, by means of the manner, a phase can be adjusted using a bias voltage, thereby accurately recovering clock information.
