ABSTRACT:
A phase comparison circuit for outputting a phase difference signal indicating a phase difference between a data signal and a clock signal is disclosed. The disclosed phase comparison circuit includes: a detection part for outputting a plurality of signals indicating phases of the data signal according to different decision threshold levels; a phase comparison part for outputting phase difference signals each indicating a phase difference between a signal in the plurality of signals output from the detection part and the clock signal; and a control part for determining whether to output a particular phase difference signal in the phase difference signals by using the whole or a part of the phase deference signals.
