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
!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.
!Absolute maximum ratings (Ta = 25°C, In measurement circuit.)
