路。[Claims for Utility Model Registration] In a digital phase synchronized circuit that performs phase synchronization by controlling the division ratio of a variable frequency divider, the division ratio is fixed at the beginning of phase synchronization to generate an asynchronous output signal. a first means for quantizing the phase difference between the input signal and the output signal into binary information and outputting the same, and detecting a change point of the binary information; and a detection method for the second means. A digital phase synchronization circuit characterized in that it comprises second means for switching to phase synchronization for controlling differentiation of the variable frequency divider based on the result.
