The CD4046B micropower phase-locked loop (PLL) consists of a low power linear voltage-controlled oscillator (VCO) a source follower a zener diode and two phase comparators The two phase comparators have a common signal input and a common comparator input The signal input can be directly coupled for a large voltage signal or capacitively coupled to the self-biasing amplifier at the signal input for a small voltage signal Phase comparator I an exclusive OR gate provides a digital error signal (phase comp I Out) and maintains 90 phase shifts at the VCO center frequency Between signal input and comparator input (both at 50% duty cycle) it may lock onto the signal input frequencies that are close to harmonics of the VCO center frequency Phase comparator II is an edge-controlled digital memory network It provides a digital error signal (phase comp II Out) and lock-in signal (phase pulses) to indicate a locked condition and maintains a 0 phase shift between signal input and comparator input The linear voltage-controlled oscillator (VCO) produces an output signal (VCO Out) whose frequency is determined by the voltage at the VCOIN input and the capacitor and resistors connected to pin C1A C1B R1 and R2 The source follower output of the VCOIN (demodulator Out) is used with an external resistor of 10 kX or more The INHIBIT input when high disables the VCO and source follower to minimize standby power consumption The zener diode is provided for power supply regulation if necessary
