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% 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. Applications • 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

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
