Working Principles

The HCF4046M013TR operates based on the principle of a Phase-Locked Loop (PLL). It compares the phase difference between an input reference signal and a feedback signal generated by the VCO. The phase comparator produces an error voltage, which is then filtered and used to control the VCO's frequency. This feedback loop ensures that the output frequency remains locked to the reference signal.
