NTE7200 Overview
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 posite sig‐ nals, an FM modulator that creates FM signals, and an RF amplifier. The stereo modulator develops posite signals made up of a MAIN (L+R) signal, a SUB (L-R) signal and a pilot (19kHz) signal using 38kHz crystal oscillators.
