Part Details:

LM565/LM565C May 1999 LM565/LM565CPhase Locked Loop Phase General Description n 0.2% linearity of demodulated output n Linear triangle wave with in phase zero crossings The LM565 and LM565C are general purpose phase locked available loops containing a stable, highly linear voltage controlled os- n TTL and DTL compatible phase detector input and cillator for low distortion FM demodulation, and a double bal- square wave output anced phase detector with good carrier suppression. The Locked VCO frequency is set with an external resistor and capacitor, n Adjustable hold in range from ±1% to > ±60% and a tuning range of 10:1 can be obtained with the samecapacitor. The characteristics of the closed loop Applications system -- bandwidth, response speed, capture and pull in n Data and tape synchronization range -- may be adjusted over a wide range with an external n Modems Loop resistor and capacitor. The loop may be broken between the n FSK demodulation VCO and the phase detector for insertion of a digital fre- n FM demodulation quency divider to obtain frequency multiplication. n Frequency synthesizer The LM565H is specified for operation over the -55°C to n Tone decoding +125°C military temperature range. The LM565CN is speci-fied for operation over the 0°C to +70°C temperature range. n Frequency multiplication and division n SCA demodulators Features n Telemetry receivers n Signal regeneration n 200 ppm/°C frequency stability of the VCO n Coherent demodulators n Power supply range of ±5 to ±12 volts with 100 ppm/% typical Connection Diagrams Metal Can Package Dual-in-Line Package DS007853-2 DS007853-3 Order Number LM565H Order Number LM565CN
