General Purpose Phase Lock Loop (PLL)

The NE565N is a general purpose Phase Lock Loop (PLL) in a 14-Lead DIP type package containing a stable, highly linear voltage controlled oscillator (VCO) for low distortion FM demodulation, and a double balanced phase detector with good carrier suppression. The VCO frequency is set with an external resistor and capacitor, and a tuning range of 10:0 can be obtained with the same capacitor. The characteristics of the closed loop systembandwidth, response speed, capture and pull-in range may be adjusted over a wide range with an external resistor and capacitor. The loop may be broken between the VCO and the phase detector for insertion of a digital frequency divider to obtain frequency multiplication.
