Abstract
A clock generation apparatus is provided with a frequency phase error calculation circuit, whereby a clock synchronized with burst lock and a line lock clock can be simultaneously generated by a DTOon the basis of frequency information of a DTOand phase error information from a phase comparatorand a digital LPF. Therefore, the clock generation apparatus can cope with a system that required plural clocks, and frequency spread is easily carried out by generating spread information by a frequency spread information generation circuit, and adding it in the DTO. As a result, interference to a video terminal from the clock can be reduced, and performance of a video terminal such as a television receiver can be exploited.
