Intergrated Circuit

FM Stereo Transmitter

Description:

The NTE7200 is a monolithic intergrated circuit in an 18-Lead DIP type package designed for use

as a stereo transmitter. This device consists of a stereo modulator that creates stereo composite sig‐

nals, an FM modulator that creates FM signals, and an RF amplifier. The stereo modulator develops

composite signals made up of a MAIN (L+R) signal, a SUB (L-R) signal and a pilot (19kHz) signal

using 38kHz crystal oscillators.

The FM modulator has carriers on the FM broadcast band (75 to 108MHz).

The RF amplifier transmits the stereo encoded FM signals and is also a buffer for the FM modulator.

The stereo transmitter is equipped with a constant voltage pin for a variable capacitor that is used to

finly adjust the FM frequency.

Features:

D Low Operating Voltage Range (1.0V to 2.0V)

D Low Power Consumption (3mA Typ)

D Few External Components Required

Applications:

D FM Stereo Transmitters

D Wireless Microphones
