CD4046 Micropower Phase Locked Loop IC DIP-16 Package

The CD4046 is a micropower phase-locked loop (PLL) IC in a DIP-16 package, designed for frequency synchronization and signal demodulation. It integrates a voltage-controlled oscillator (VCO) and two phase comparators, making it ideal for hobbyists and engineers building frequency-based circuits.

Specifications

• Supply voltage: 3V to 15V DC
• Operating frequency: up to 1.4 MHz (at 10V supply)
• Two phase comparators: Type I (XOR) and Type II (edge-triggered)
• Built-in VCO with linear frequency control
• Low power consumption: typically 0.7 mW at 5V
• Package: 16-pin DIP

Compatible with

• Arduino Uno, Nano, Mega
• ESP32, ESP8266
• Raspberry Pi (via GPIO or I2C)
• STM32 microcontrollers
• 555 timer circuits and other logic families

What you can build with it

• Frequency synthesizer for signal generation
• FSK demodulator for data communication
• Tone decoder for DTMF or touch-tone applications

Frequently Asked Questions

What is the difference between the two phase comparators on the CD4046?

Phase comparator I (XOR gate) works best with 50% duty cycle signals and locks to a 90° phase difference. Phase comparator II (edge-triggered) locks to 0° phase difference and can handle a wider range of duty cycles.
