NTE989
Integrated Circuit
General Purpose Phase Lock Loop (PLL)
Description:
The NTE989 is a general purpose Phase Locked Loop (PLL) in a 14–Lead DIP type package contain-
ing 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 frequen-
cy multiplication.
Features:
D 200ppm/°C frequency stability of the VCO
D Power supply range of ±5 to ±12 volts with 100ppm/% typical
D 0.2% linearity of demodulated output
D Linear triangle wave with in phase zero crossings available
D TTL and DTL compatible phase detector input and square wave output
D Adjustable hold in range from ±1% to > ±60%
Applications:
D Data and tape synchronization
D Modems
D FSK demodulation
D FM demodulation
D Frequency synthesizer
D Tone decoding
D Frequency multiplication and division
D SCA demodulators
D Telemetry receivers
D Signal regeneration
D Coherent demodulators
