Abstract
PURPOSE: To enable lock-in on synchronization even if the frequency of the voltage control oscillator in a PLL circuit is deviated from input clock pulse signal, by using such a phase comparator that is capable of detecting the phase of two signals even if the phase difference of two signals deviates in pulse time interval duration at the lock-in of period.
