CD4046BM/CD4046BC Micropower Phase-Locked Loop

General Description

The CD4046B micropower phase-locked loop (PLL) con-

sists of a low power, linear, voltage-controlled oscillator

(VCO), a source follower, a zener diode, and two phase

comparators. 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 sig-

nal input for a small voltage signal.

The INHIBIT input, when high, disables the VCO and source

follower to minimize standby power consumption. The zener

diode is provided for power supply regulation, if necessary.

Features

Wide supply voltage range

3.0V to 18V

Low dynamic

power consumption

VCO frequency

70 mW (typ.) at

1.3 MHz (typ.) at V

10 kHz, V

Phase comparator I, an exclusive OR gate, provides a digital

error signal (phase comp. I Out) and maintains 90 phase

10V

Low frequency drift

with temperature

High VCO linearity

0.06%/ C at V

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.

1% (typ.)

Applications

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.

FM demodulator and modulator

Frequency synthesis and multiplication

Frequency discrimination

Data synchronization and conditioning

Voltage-to-frequency conversion

Tone decoding

The linear voltage-controlled oscillator (VCO) produces an

output signal (VCO Out) whose frequency is determined by

the voltage at the VCO input, and the capacitor and resis-

tors connected to pin C1 , C1 , R1 and R2.

FSK modulation

Motor speed control

The source follower output of the VCO (demodulator Out)

is used with an external resistor of 10 kX or more.
