The IC 4046 is a Phase-locked loop IC of CMOS digital (combined analog and digital chip).

A Phase-locked loop(PLL) has a voltage-controlled oscillator(VCO).

The VCO signal and an input signal are sent to a phase comparator which generates an error voltage part to any difference in frequency between two signals.

The error voltage adjusts the VCO frequency to match that of the input signal.

Thus the PLL can track an input signal.

Or only the VCO function can be used. Read more>>
