Overview

MC74HC4046A Phase-Locked Loop High−Performance Silicon−Gate CMOS The MC74HC4046A is similar in function to the MC14046 Metal gate CMOS device.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC4046A phase−locked loop contains three phase comparators, a voltage−controlled oscillator (VCO) and unity gain op−amp DEMOUT.
The comparators have two common signal inputs, COMPIN, and SIGIN.
Input SIGIN and COMPIN can be used directly coupled to large voltage signals, or indirectly coupled (with a series capacitor to small voltage signals).
The self−bias circuit adjusts small voltage signals in the linear region of the am...
