LM565
LM565 is Phase Locked Loop manufactured by National Semiconductor.
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. n 0.2% linearity of demodulated output n Linear triangle wave with in phase zero crossings available n TTL and DTL patible phase detector input and square wave output n Adjustable hold in range from ± 1% to > ± 60%
Applications n n n n n n n n n n n Data and tape synchronization Modems FSK demodulation FM demodulation Frequency synthesizer Tone decoding Frequency multiplication and division SCA demodulators Telemetry receivers Signal regeneration Coherent demodulators
