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 components. It is available for many applications due to the
varieties of setting such as transmission output by serial data input.
!
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 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.
