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 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
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
Y Wide supply voltage range
Y Convenient mini-DIP package
Y TRI-STATE phase-comparator output (comparator II)
Y 200 mV input voltage (signal in) sensitivity (typical)
