Abstract
A clock recovery circuit includes a delay line circuit configured to output a plurality of first clocks having different phases obtained by delaying an input data signal, a register circuit configured to determine and write received data in the input data signal based on the first clocks, and a control circuit configured to control the writing of the data in the register circuit based on transitions of the input data signal.
