Product Summary

The NTE989 is a general purpose Phase Locked Loop (PLL) in a 14--Lead DIP package 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 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.

  • 200ppm/°C frequency stability of the VCO
  • Power supply range of &plusnm;5 to &plusnm;12 volts with 100ppm/% typical
  • 0.2% linearity of demodulated output
  • Linear triangle wave with inphase zero crossings available
  • TTL and DTL compatible phase detector input and square wave output
  • Adjustable hold in range from &plusnm;1% to > &plusnm;60%
  • Supply voltage: +12V
  • Power dissipation:* 300mW
  • Differential input voltage: &plusnm;1V
  • Operating temperature range: 0°C to +70°C
  • Storage temperature range: --65°C to +150°C
  • Lead temperature (soldering, 10 sec): +300°C
