Abstract
A clock recovery circuit includes: a multi-phase clock generating circuit configured to generate multi-phase clocks having different phases; a plurality of switch elements configured to control coupling between each of the multi-phase clocks and an output node; and a switch control circuit configured to compare phases of the multi-phase clocks and input data and control, to an on-state, at least two switch elements of the plurality of switch elements corresponding to at least two clocks whose phase difference falls within a given range, wherein the at least two clocks selected through the at least two switch elements controlled to the on-state are subjected to phase interpolation to recover an output clock.
