TIMING SIGNAL GENERATOR FOR TELEVISION RECEIVER

摘要

PROBLEM TO BE SOLVED: To generate a more stable vertical pulse signal by making jitter of various vertical timing signals possible to be cancelled by sampling a vertical synchronizing signal by a horizontal synchronizing signal according to various signals. SOLUTION: The vertical synchronizing signal is first delayed in a phase in which no problem is caused by the jitter from a sampling point of the horizontal synchronizing signal by a delay circuit 12. Next, a timing signal based on the vertical synchronizing signal of a video signal is generated by sampling the delayed vertical synchronizing signal by a clock signal by a vertical address counter 17.
