Overview
NTE788 Integrated Circuit IF System for FM Receiver Description: The NTE788 is a monolithic integrated circuit in a 16–Lead DIP type package that provides all the functions of a comprehensive FM–IF system.
This device features a three–stage FM–IF amplifier/limiter configuration with level detectors for each stage, a doubly–balanced quadrature FM detector, and an audio amplifier that features the optional use of a muting (squelch) circuit.
The advanced circuit design of the IF system includes desirable deluxe features such as delayed AGC for the RF tuner, an AFC drive circuit, and an output signal to drive a tuning meter and/or provide stereo switching logic.
In addition, internal power supply regulators maintain a nearly constant current drain over the voltage supply range of +8.
5V to +16V.
Features: D Exceptional limiting sensitivity: 12µV typ.
at –3dB point D Low distortion: 0.
1% typ.
(with double–tuned coil) D Single–coil tuning capability D Improved S + N/N Radio D Externally programmable recovered audio level D Provides specific signal for control of interchannel muting (squelch) D On channel step for search control D Provides programmable AGC voltage for RF amplifier D Internal supply–voltage regulators D Externally programmable “ON” channel step width, and deviation at which muting occurs Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) DC Supply Voltage Between Pin11 and Pin4 .
