ML12040
Phase–Frequency
Detector
Legacy Device:
Motorola MC12040
The ML12040 is a phase–frequency detector intended for
use in systems requiring zero phase and frequency difference
at lock. In combination with a voltage controlled oscillator
(such as the ML12149), it is useful in a broad range of
phase–locked loop applications.
• Operating Frequency = 80 MHz Typical
• Operating Temperature Range TA = 0° to 75°C

TRUTH TABLE
This is not strictly a functional truth table; i.e., it does not cover all possible
modes of operation. However, it gives a sufficient number of tests to
ensure that the device will function properly in all modes of operation.
