Working Principles
The working principle of MC74HC4046ANG revolves around the phase-locked loop (PLL) concept. It uses a phase comparator to compare the phase difference between two input signals. The voltage-controlled oscillator (VCO) generates an output signal with a frequency proportional to the phase difference. The charge pump adjusts the control voltage to the VCO, ensuring the output frequency remains locked to the input signals.
