BH1417F Wireless Audio-Link

BH1417F Multimedia ICs Wireless Audio Link IC BH1417F The BH1417F 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.

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 controls data input in parallel (4bits, 14ch for North America). !Absolute maximum ratings (Ta = 25°C, In measurement circuit.)
