BH1414K Wireless Audio-Link

BH1414K Multimedia ICs Wireless Audio Link IC BH1414K The BH1414K is a FM stereo transmitter IC that uses a simple configuration. This IC consists of a stereo modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. A high S/N ratio and good timbre transmitter circuit can be composed with a few componen.

Features

1) It is possible to improve the timbre because it has the pre-emphasis circuit, limiter circuit, and the 19kHz/38kHz low-pass trap filter circuit. 2) Built-in pilot-tone system FM stereo modulator circuit. 3) The transmission frequency is stable because it has a PLL system for the FM transmitter circuit. 4) PLL data input (CE, CK, DA) by serial input. 5) It is possible for input level setting, monaural operation and output ON/OFF control by serial input. 6) It is possible for the transmission output control. !Absolute maximum ratings (Ta = 25°C) Parameter Supply voltage Power dissipation Sto.
