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.
