<P>PROBLEM TO BE SOLVED: To provide bust lock clocks and line-locked clocks matched with respective signals without increasing the number of PLLs even when a plurality of different image signals are inputted. <P>SOLUTION: The clock generation apparatus, which is provided with a frequency phase computing circuit 120, simultaneously generates not only a clock synchronizing with a burst lock from a DTO 10 based on frequency information from the DTO 10 and phase error information from a phase comparator 7 and a digital LPF 8 but also a line-locked clock from a DTO 121 and can cope with a system requiring a plurality of clocks. Since frequency diffusion is easily performed by creating diffusion information in a frequency diffusion information generation circuit 90 and adding the diffusion information by the DTO 121, the interference of clocks to a video terminal is reduced and the performance of the video terminal such as a television receiver is taken out. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
