BH1415F Datasheet Wireless Audio-link

Manufacturer: ROHM

Overview: BH1415F Audio ICs Wireless Audio Link IC BH1415F The BH1415F is a FM stereo transmitter IC that transmits simple configuration. The IC consists 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 radiates FM wave on the air by modulating the carrier signal with a composite signal. !Applications CD changer, Car TV, Car navigation, Wireless speakers, Personal computer (sound board), Game machine !
