Clock signal generation circuit, display panel module, image sensor apparatus, and electronic apparatus

摘要

A clock signal generation circuit of a delay locked loop type includes a delay line configured to delay a first clock signal to generate a second clock signal; a delay amount controller configured to change the amount of delay in the delay line in such a manner that a phase of the second clock signal is in synchronization with a phase of the first clock signal; a pseudo-lock detection section configured to detect a pseudo-locked state of the first clock signal and the second clock signal; and a pseudo-locked state release section configured to change the amount of delay in the delay line in a case that the pseudo-locked state is detected.
