CD4046 Phase-Locked Loop CMOS

Description

CD4046 is a Micropower Phase-Locked Loop (PLL) that comes with a phase detector for comparing the phase of the output signal with the input signal and adjust them in order to make the matching signals from both ends. It comes with a common comparator input and a common signal input amplifier between a low-power linear voltage-controlled oscillator (VCO) and two different phase comparators. The input signal can be operated in two ways: capacitively layered with a self-biasing amplifier for creating a small voltage signal or directly coupled for a large voltage signal. The VCO (Voltage Controlled Oscillator) is an integral part of the IC that mainly generates oscillated frequency based on the applied input. The generated frequency is then used for phase modulation. The chip features two phase comparators i.e. Phase Comparator I and Phase Comparator II. They are also known as Phase Detectors.
