The BH1417F is a FM stereo transmitter IC that transmits simple configuration. The IC consists of a stereo modulator forgenerating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulatorgenerates 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.Frequency is set for North America.!ApplicationsWireless speakers, Personal computer(sound board), Game machine, CD changer, Car TV, Car navigation!Features1) 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 controls data input in parallel (4bits, 14ch for North America).
