NJW1134

AUDIO PROCESSOR

I GENERAL DESCRIPTION

I PACKAGE OUTLINE

The NJW1134 is a sound processor includes all of the

functions required to process the audio signal for TV, such

as tone control, balance, volume, mute, and AGC functions.

Also the NJW1134 performs BBE sound enhancement

and SRS 3D-Stereo. The BBE regenerates high definitive

and nearly real sound, and SRS 3D-Stereo regenerates 3D

surround sound with only two speakers.

All of the internal status and variables are controlled by

NJW1134GK1

I²C BUS interface.
