Working Principles

The working principle of CD74HC4046AM96E4 revolves around its phase comparators, voltage-controlled oscillator, charge pump, and PLL filter. The phase comparators compare the phase difference between two input signals and generate an error voltage. This error voltage controls the VCO, which generates an output frequency proportional to the control voltage. The charge pump converts the error voltage into a current, which is then filtered by the PLL filter to provide a stable control voltage for the VCO.
