<P>PROBLEM TO BE SOLVED: To suppress a phase jump caused when two clock generating sections are switched. <P>SOLUTION: The frame pulse generator is provided with: the first clock generating section 10 for generating a frame pulse and a clock on the basis of a first external clock; the second clock generating section 20 for generating a frame pulse and a clock on the basis of a second external clock; and a monitor control section 30 for outputting a signal whereby one of the first and second clock generating sections 10, 20 is selected to be a master and the other of the first and second clock generating sections 10, 20 is selected to be a slave on the basis of the states of the first and second clock generating sections 10, 20, and each of the first and second clock generating sections 10, 20 corrects the phase of the frame pulse generated by its own clock generating section on the basis of the clock generated by the other clock generating section when receiving the signal for designating the slave. <P>COPYRIGHT: (C)2004,JPO |
