Title: Phase locked loop circuit
Inventor: KOGA HISAHIRO
IPC: H03L7/10
Filed: 1990-06-14
Abstract: PURPOSE:To reduce the synchronization lock time by synchronizing an input signal with an oscillation signal in phase when a phase difference between the input signal and the oscillation signal is a prescribed value or over and by inverting the oscillation signal from a voltage controlled oscillator means so as to synchronize the input signal with the oscillating signal in opposite phase when the phase difference between the input signal and the oscillation signal is a prescribed value or below. CONSTITUTION:The phase locked loop is provided with a voltage controlled oscillator means 3, a phase difference discrimination means, an inversion means and a phase comparison control means comparing a phase of an output signal of the inversion means with a phase of an input signal so as to control the voltage controlled oscillator means 3. When a phase difference between the input signal and the oscillation signal is a prescribed value or over, the input signal and the oscillating signal are synchronized in opposite phase, and when a phase difference between the input signal and the oscillation signal is a prescribed value or below, the input signal and the oscillating signal are synchronized in phase. However, when the input signal and the oscillating signal are synchronized in opposite phase, the inverting signal of the voltage controlled oscillator means 3 is outputted. Thus, the maximum synchronization lock time is reduced to nearly a half at most without varying the integration time constant and the phase control variable.
