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.

Features

1) It is possible to improve the timbre because it has the pre-emphasis circuit, limiter circuit, and the low-pass filter circuit.

2) Built-in pilot-tone system FM stereo modulator circuit.

3) The transmission frequency is stable because it has a PLL system FM transmitter circuit.

4) PLL data input (CE, CK, DA) by serial input.

Applications

CD changer, Car TV, Car navigation, Wireless speakers, Personal computer (sound board), Game machine
