MM54C932/MM74C932 Phase Comparator

General Description

The MM74C932/MM54C932 consists of two independent

output phase comparator circuits. The two phase compara-

tors have a common signal input and a common comparator

input. The signal input can be directly coupled for a large

voltage signal, or capacitively coupled to the self-biasing

amplifier at the signal input for a small voltage signal.

Phase comparator II is an edge-controlled digital memory

network. It provides a digital error signal (phase comp. II

out) and lock in signal (phase pulses) to indicate a locked

condition and maintains a 0 phase shift between signal in-

put and comparator input.

Features

Phase comparator I, an exclusive-OR gate, provides a digi-

tal error signal (phase comp. I out) and maintains 90 phase

shifts at the VCO center frequency. Between signal input

and comparator input (both at 50% duty cycle), it may lock

onto the signal input frequencies that are close to harmon-

ics of the VCO center frequency.
