Abstract
A phase-locked loop circuit comprising a received data counter for counting received clock signals reproduced according to sent data count values output from a transmitter, a subtracter for subtracting the output of the received data counter from an entered sent data count value, first and second attenuators for attenuating the output of the subtracter, an integrator for integrating the output of the second attenuator, an adder for adding the output of the first attenuator to the output of the integrator, a converter for converting the output of the adder into the corresponding voltage signal, and a voltage control oscillator that is controlled by the output of the converter and outputs a received clock signal to be supplied to the received data counter.
