Abstract: PURPOSE:To decrease the frequency jump of a VCO by minimizing the first phase difference between two signals inputted to a phase comparator after reapplication of power supply in a phase locked oscillator in intermittent operation by the intermission of power supply. CONSTITUTION:A zero detection circuit 14 outputting a zero phase signal detecting that a phase difference between clocks inputted to a reference frequency divider 2 and a frequency divider 7 is nearly zero and a reset pulse generating circuit 15 applying initial set to the reference frequency divider 2 and the frequency divider 7 synchronously with the first zero phase signal after the appliciation of power, are added newly. In applying power again, the zero phase detection circuit 14 detects the zero phase between the clocks of a reference oscillator 1 and a VCO 5 and the reset pulse generating circuit 15 outputs a pulse. In this case, since the reference frequency divider 2 and the frequency divider 7 are set in initial state, the phases of the next frequency division carrier signal outputted from both the frequency dividers are made nearly coincident. Thus, an error signal outputted from a phase comparator 3 is decreased.
