Clock reproducing device and clock reproducing method, which utilize a frequency difference and receiving interval

摘要

The clock reproducing device includes a control device which generates a control signal for decreasing a clock frequency difference between a transmitter and a receiver according to a clock information difference between the transmitting clock information and reproduced clock information and a receiving interval of the transmitting clock information, thereby the clock reproducing device controls a reproduced clock frequency of a reproduced clock output device. The clock reproducing device carries out appropriate frequency control regardless of the transmitting interval of the transmitting clock information received from the transmitter.
