AUDIO PROCESSOR

■ GENERAL DESCRIPTION

The NJW1135 is audio processor with sound

■ PACKAGE OUTLINE

enhancement (BBE). It includes all of the functions

processing audio signal for TV, such as tone control,

balance, volume, mute, and AGC functions.

Also the NJW1135 performs surround and sound

enhancement. The sound enhancement regenerates high

definitive and nearly real sound.

All of the internal status and variables are controlled by

I²C BUS interface.
