In a receiving clock reproducing method, an estimated value of delay time fluctuation of a received signal is estimated at intervals defined by transmitting clock included in the received signal. To estimate the estimated value, an oscillator counter counts pulses of a reference clock supplied from an independent oscillator while a reading counter counts pulses of the receiving clock. The estimated value is used to control a voltage controlled oscillator for producing the receiving clock.
