General Description
The LM565 and LM565C are general purpose phase locked loops containing a stable,
highly linear voltage controlled oscillator 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 10:1 can be obtained with the same
capacitor. The characteristics of the closed loop system-bandwidth, 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.
The LM565H is specified for operation over the -55°C to +125°C military temperature
range. The LM565CN is specified for operation over the 0°C to +70°C temperature range.
Features
200 ppm/°C frequency stability of the VCO
Power supply range of ±5 to ±12 volts with 100 ppm/% typical
0.2% linearity of demodulated output
Linear triangle wave with in phase zero crossings available
TTL and DTL compatible phase detector input and square wave output
Adjustable hold in range from ±1% to > ±60%
