Patent JP-H04111532-A (JP)
Title: Pll circuit
Inventor: HAYASHIDA FUJIO
IPC: H03L7/10
Filed: 1990-08-30
Abstract: PURPOSE:To allow the frequency and the phase of an output signal to follow up those of a reference clock signal by temporarily adding a voltage, which reduces the phase difference, to a voltage controlled oscillator in the case of the quick change of the phase of the reference clock signal due to some cause. CONSTITUTION:A first switch 2 which connects or disconnects a reference clock input terminal and the other input terminal of a phase comparator and an adder 6 which adds the output signal of an amplifier 5 and a prescribed control voltage and outputs the result to a voltage controlled oscillator 7 are provided. If the phase of the reference clock signal is deviated from that of the output signal of a frequency divider 9 by a prescribed value or larger, the switch 2 is opened. When the phase of the reference clock signal leads that of the output signal of the frequency divider 9 by a prescribed value or larger, the voltage to raise the oscillation frequency of the voltage controlled oscillator 7 is outputted to the adder 6 as the control voltage; but when the phase of the reference clock signal is delayed behind that of the output signal of the frequency divider 9, the voltage to reduce the oscillation frequency us outputted to the adder 6 as the control voltage. Thus, the frequency and the phase of the output signal follow up those of the reference clock signal.
