<P>PROBLEM TO BE SOLVED: To provide a clock data reproduction circuit capable of preventing the occurrence of a phenomenon in which a reference clock signal and a frequency temporarily collapse greatly when coming into a non-signal section between burst signals; and to provide a reproducing method, and a station-side device using the reproduction circuit. <P>SOLUTION: A frequency multiplication part 110 multiplies the frequency of the reference clock signal to a frequency corresponding to a data signal to be a multiplied clock signal, and uses an input selecting part 111 to selects an input. That is, when a burst signal as a data signal is input, a reproduction clock signal is generated so as to synchronize a phase with the input burst signal, and when the burst signal is not input, the reproduction clock signal is generated so as to synchronize a phase with the multiplied clock signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
