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 DEM

OUT

. The comparators have two common signal inputs,

COMP

, and SIG

. Input SIG

and COMP

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 amplifier. Phase comparator

1 (an exclusive OR gate) provides a digital error signal PC1

OUT

and

maintains 90 degrees phase shift at the center frequency between

SIG

and COMP

signals (both at 50% duty cycle). Phase

comparator 2 (with leading−edge sensing logic) provides digital error

signals PC2

OUT

and PCP

OUT

and maintains a 0 degree phase shift

between SIG

and COMP

signals (duty cycle is immaterial). The

linear VCO produces an output signal VCO

OUT

whose frequency is

determined by the voltage of input VCO

signal and the capacitor

and resistors connected to pins C1A, C1B, R1 and R2. The unity gain

op−amp output DEM

OUT

with an external resistor is used where the

VCO

signal is needed but no loading can be tolerated. The inhibit

input, when high, disables the VCO and all op−amps to minimize

standby power consumption.

Applications include FM and FSK modulation and demodulation,

frequency synthesis and multiplication, frequency discrimination,

tone decoding, data synchronization and conditioning,

voltage−to−frequency conversion and motor speed control.
