74HC4046A; 74HCT4046A
Phase-locked loop with VCO
Rev. 4 — 6 August 2019
Product data sheet
1. General description
The 74HC4046A; 74HCT4046A is a high-speed Si-gate CMOS device. It is specified in compliance
with JEDEC standard no 7A.
2. Features and benefits
Low power consumption
VCO-Inhibit control for ON/OFF keying and for low standby power consumption
Center frequency up to 17 MHz (typical) at VCC = 4.5 V
Choice of three phase comparators:
PC1: EXCLUSIVE-OR
PC2: Edge-triggered J-K flip-flop
PC3: Edge-triggered RS flip-flop
Excellent Voltage Controlled Oscillator (VCO) linearity
Low frequency drift with supply voltage and temperature variations
Operating power supply voltage range:
VCO section 3.0 V to 6.0 V
Digital section 2.0 V to 6.0 V
Zero voltage offset due to operational amplifier buffering
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
3. Applications
FM modulation and demodulation
Frequency synthesis and multiplication
Frequency discrimination
Tone decoding
Data synchronization and conditioning
Voltage-to-frequency conversion
Motor-speed control
