Abstract
A semiconductor integrated circuit includes: a phase synchronization circuit configured to be synchronized with a reference clock signal and to generate a synchronization clock signal by multiplying the reference clock signal; an edge detection circuit configured to detect an edge at which a signal waveform of the reference clock signal changes at a timing of the synchronization clock signal and to output an edge detection signal indicating the timing at which the edge has been detected; and a clock division circuit configured to be reset at a timing based on the edge detection signal and to generate a divided clock signal by dividing the synchronization clock signal.
