Overview
The MC14046BDWR2G, produced by onsemi, is a phase locked loop (PLL) integrated circuit that includes two phase comparators, a voltage-controlled oscillator (VCO), a source follower, and a zener diode. This device is designed for various applications requiring precise frequency control and synchronization. It features two phase comparators: one is an exclusive OR gate with a 90° phase shift at the center frequency, and the other switches on rising edges with a 0° phase shift. The VCO produces an output signal whose frequency is controlled by the input voltage and external components connected to it. The source follower output is used where the VCO input signal is needed without loading the circuit. The inhibit input allows for disabling the VCO and source follower to minimize standby power consumption.
