SL74HC4046

Phase-Locked Loop

High-Performance Silicon-Gate CMOS

The device inputs are compatible with standard CMOS outputs;

with pullup resistors, they are compatible with LS/ALSTTL outputs.

The SL74HC4046 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_OUTand

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

ORDERING INFORMATION

and PCP_OUTand maintains a 0 degree phase shift between SIG and

SL74HC4046D SOIC

COMP_INsignals (duty cycle is immaterial). The linear VCO produces an

output signal VCO_OUTwhose frequency is determined by the voltage of

input VCO_INsignal and the capacitor and resistors connected to pins

T_A= -55° to 125° C for all packages

C1A, C1B, R1 and R2. The unity gain op-amp output DEM_OUTwith an external resistor is used where the VCO_IN

signal is needed but no loading can be tolerated. The inhibit input, when high, disables the VCO and all on-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.
