ABSTRACT In an intermittently operative phase-locked loop, in order to prevent the oscillator frequency from signifi- cantly changing at the time of turning on of an electric power source, a point in time at which a phase difference between clock signals respectively fed to a reference frequency divider and to a freuqency divider for dividing the output frequency of a voltage-controlled oscillator becomes substantially zero is detected, and the two frequency dividers are initialized when the above-mentioned point in time is detected after turning of the electric power source.
