NJW1144
AUDIO PROCESSOR
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJW1144 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 NJW1144 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.
