The NE565 Phase-Locked Loop (PLL) is a self-contained, adaptable filter and demodulator for the frequency range from 0.001Hz to 500kHz. The circuit comprises a voltage-controlled oscillator of exceptional stability and linearity, phase comparator, an amplifier and a low pass filter as shown in the Block Diagram. The center frequency of the VCO; this frequency can be adjusted externally with a resistor or a capacitor. The low pass filter, which determines the capture characteristics of the loop, is formed by an internal resistor and external capacitor.
Usage: Frequency Shift Keying (FSK), Frequency Multiplication, SCA (Background Music) Decoder, etc.
