ABSTRACT:
A locking state detector includes a phase comparing unit configured to compare a reference clock signal and a feedback clock signal to generate a first phase difference distinction signal to distinguish a first phase difference range, and a second phase difference distinction signal to distinguish a second phase difference range wider than the first phase difference range, and a locking state setting unit configured to generate a locking state signal in response to the first phase difference distinction signal and the second phase difference distinction signal.
