Description

The BH1415S/F are FM stereo transmitter ICs that transmit simple configuration. The ICs consist of a stereo modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulator generates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator. The FM transmitter BH1415S radiates FM wave on the air by modulating the carrier signal with a composite signal.
