ABSTRACT:
A clock switching device capable of automatic switching to a clock distribution system for back-up without interrupting processing of the device, which includes an abnormality detection unit which detects lack of coincidence in a logical level between a current clock pulse and a one-cycle preceding clock pulse as abnormality in a waveform on the basis of a plurality of cock pulses, a phase adjustment unit for switching which adjusts a phase of other clock pulse to a phase of a clock pulse being output, and a switching unit which switches to and outputs other clock pulse whose phase is adjusted by the phase adjustment unit for switching based on detection of lack of coincidence in a logical level by said abnormality detection unit.
