Texas Instruments CD4046BE CMOS Micropower Phase Locked Loop 2.4MHz DIP 16

The Texas Instruments CD4046BE CMOS Micropower Phase Locked Loop is a 16-pin DIP phase-locked loop IC with a supply range of 3V to 18V and a maximum operating frequency of 2.4MHz. It is designed for low power consumption and is suited to battery-powered and energy-sensitive applications across industrial, communications, and consumer electronics.

At its core, the device integrates a low-power, linear voltage-controlled oscillator (VCO) and two phase comparators that share a common signal input amplifier and comparator input. This arrangement supports different phase-detection schemes, including edge-triggered and digital-type phase comparison. A 5.2V zener diode is included on-chip for optional supply regulation.

Key Performance Specifications

• Power consumption of 70µW at a VCO frequency of 10kHz with a 5V supply
