Working Principles

The MM74HC4046MTC operates based on the principles of a Phase-Locked Loop (PLL). It compares the phase of an input signal with that of a voltage-controlled oscillator (VCO) output. The phase comparator detects any phase difference and generates a control voltage to adjust the VCO frequency accordingly. This feedback loop ensures that the output frequency remains locked to the input signal.
