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/lim-
iter 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 ste-
reo 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:
Exceptional limiting sensitivity: 12
μ
V typ. at –3dB point
Low distortion: 0.1% typ. (with double–tuned coil)
Single–coil tuning capability
Improved S + N/N Radio
Externally programmable recovered audio level
Provides specific signal for control of interchannel muting (squelch)
On channel step for search control
Provides programmable AGC voltage for RF amplifier
Internal supply–voltage regulators
Externally programmable “ON” channel step width, and deviation at which muting occurs
