MM54C932/MM74C932 Phase Comparator
General Description
The MM74C932/MM54C932 consists of two independent
output phase comparator circuits. The two phase comparators 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 digital error signal (phase comp. I out) and maintains 90
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 harmonics 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
put and comparator input.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
