NJW1172

AUDIO PROCESSOR

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW1172 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 NJW1172 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

I²C BUS interface.
