Product Summary

The LM565H is a general purpose phase locked loop. It contains 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 of the LM565H is set with an external resistor and capacitor, and a tuning range of 10:1 can be obtained with the same capacitor. The applications of the LM565H include: 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.
