Abstract
A clock and data recovery device includes an extraction circuit and a phase detection circuit. The extraction circuit extracts transition information including data information corresponding to a value of data and edge information corresponding to transition of the value of the data, from a multivalued input data signal subjected to pulse amplitude modulation in synchronization with a clock from an oscillator. The phase detection circuit uses transition information selected based on a predetermined condition, when executing a phase error determination of the clock with respect to the input data signal based on the transition information extracted by the extraction circuit.
