NTE1056
Integrated Circuit
FM Stereo Multiplex Demodulator

Description:
The NTE1056 is a monolithic integrated circuit FM multiplex stereo demodulator designed for use in
FM stereos, phonographs and radio receivers. A multiplex stereo demodulator circuit generally consists
of four main circuits, a composite signal amplifier, 19KHz pilot signal filter, 38KHz subcarrier generator
and either a matrix or a switching circuit which seperates the composite signal into the right
and left audio channels. In addition to these circuits, an automatic stereo-monaural switching circuit,
stereo signal indicator circuit, muting circuit, separation control circuit and SCA circuit are also included as supplemental circuits. The NTE 1056 is designed to include both main stereo demodulator
circuits and supplemental circuits on a common monolithic substrate, and is supplied in a 14 lead DIP.
