Working Principles

The NLVHC4046ADTR2G operates based on the principle of phase-locked loop (PLL). It compares the phase and frequency of an input reference signal with a voltage-controlled oscillator (VCO) output signal. The phase detector generates an error signal, which is filtered and used to control the VCO frequency. This feedback loop ensures that the VCO output locks onto and tracks the input reference signal.
