(Controlled 0scillator) A phase detector that detects the phase and frequency difference of the output, a loop filter that converts the output of the phase detector into a VCO control signal, and adds the output of the loop filter and the signal from the frequency selector. It is characterized by comprising an adder, a frequency selector that outputs a frequency selection signal to be added to the adder, and a VCO whose oscillation frequency is controlled by the output of the adder and generates one input signal of the phase detector.
