NJW1160
AUDIO PROCESSOR with SOUND ENHANCEMENT and SRS 3D STEREO
www.datasheet4u.com
I GENERAL DESCRIPTION
The NJW1160 is an audio processor that includes Sound
enhancement (BBE) and SRS 3D Stereo. It includes all of
the audio signal processing functions for TV such as tone
control, balance, volume, mute, and AGC .
The SRS 3D stereo technology reproduces 3D stereo
surround sound effect using only two speakers.
The sound enhancement regenerates high definitive and
nearly real sound.
All of internal status and variables are controlled by I2C
BUS interface.

3. BBE, Surround mode and "OUT" switch settings
The click noise may be generated by changing the BBE, Surround mode setting and “OUT” switch.
Provide the external circuit for avoiding the click noise on above condition.
4. External parts for BBE circuits
The constant of capacitors connected to the terminals No.2, 3, 28 and 29 are designated by BBE Sound Inc.
Do not change the constant of these capacitors without the approval of BBE Sound Inc.
5. AUX1, AUX0 Terminal
AUX1/0 are enable to control external logic circuit is
Source current
: 1mA typ. (Ta=25˚C)
Sink current
: 0.5mA typ. (Ta=25˚C)
6. Capacitor for Reference Voltage (21pin)
22µF should be recommended for ripple filter connected to Vref terminal (21pin).
Reducing this capacity may cause to reduce the maximum attenuation level and to increase the output
noise.
