Abstract
A signal recovery circuit includes an oscillator that generates a first clock of which a frequency is variable, and a feedback circuit that controls the oscillator to synchronize the first clock with input data, depending on a phase relationship between the input data and the first clock, the feedback circuit including a control portion that controls the oscillator depending on the phase relationship between the input data and the first clock, a first phase detection circuit that generates a clock phase control signal depending on the phase relationship between the input data and the first clock, an output data generation circuit that generates output data by latching the input data at a change edge of the first clock, and a lock detection circuit that outputs a lock detection signal indicating whether a state is a lock state or a non-lock state.
