Title: Clock generation circuit
Inventor: HOTTA TERUO
IPC: H04N9/45
Filed: 1986-03-10
Abstract: PURPOSE:To obtain a stable clock signal irrespective of the quantity of noise included in a video signal by selectively outputting the clock signal synchronizing with a burst signal in phase when the burst signal is included in an input signal and with a horizontal synchronizing signal except that. CONSTITUTION:A voltage control oscillator (VCO)7 corrects the phase of the first clock signal according to an incoming phase error signal to generate the first clock signal phase-locked with the burst signal. A VCO11 corrects the phase of an output signal (the second clock signal) based on the incoming phase error signal to generate the second clock signal phase-locked with the horizontal synchronizing signal. A killer detector 9 detects whether the burst signal is included or not in the video signal based on the incoming phase error signal, when the burst signal is detected, the first clock signal is selected and outputted, a more stable synchronization is obtained, and on the other hand, when the burst signal is not detected, the second clock signal is selected and outputted.
