Title: Pll demodulation circuit
Inventor: KUSANO YASUHIRO
IPC: H03D3/02
Filed: 1989-12-18
Abstract: PURPOSE:To eliminate the need for the adjustment of the circuit by applying a demodulation signal to an oscillating frequency control terminal of a voltage controlled oscillator(VCO) via a voltage control circuit. CONSTITUTION:A limiter 6 is interposed between an output terminal of a DC amplifier 4 and an input terminal of a VCO 2. Upon the receipt of an input signal (output of the DC amplifier 4) of a prescribed level or over, the limiter 6 suppresses the level of the input signal to a prescribed level to output the result as an oscillating frequency control signal Vc and in other cases, the limiter 6 outputs the input signal as it is as the oscillating frequency control signal Vc. Thus, the lock range and the capture range are made equal to each other. Since the allowable range of the lock range and the capture range is comparatively wider and more excellent, fine adjustment in circuit components 2-4 is not required.
