Functional Characteristics

The 74VHC4046MX is a phase-locked loop integrated circuit that consists of a voltage-controlled oscillator (VCO) and a phase comparator. It is designed for high-speed operation and low power consumption.

The VCO generates an output frequency that is proportional to the input control voltage. The phase comparator compares the phase of the input reference signal with the phase of the feedback signal from the VCO. The phase-locked loop locks the output frequency to the input reference frequency by adjusting the control voltage.
