P R E L I M I N ALY
AUDIO PROCESSOR with SRS 3D STEREO
■ GENERAL DESCRIPTION
The NJW1161 is an audio processor that includes 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 a 3D stereo
surround sound effect using only two speakers.
2
All of internal status and variables are controlled by I C
BUS interface.

■ APPLICATION NOTE
1. AGC (Auto Gain Control) Circuit
AGC circuit adjusts the input signal level with Boost/Attenuate circuit. AGC boost the low input signal level
and attenuate high input signal level automatically.
2
The AGC flat levels (150mV, 300mV, 400mV and 540mV) are selectable via I C bus. (Refer to the following
figure.)

Smoothing circuit of Attenuate
Smoothing circuit of Boost
Attack and recovery time in the attenuation processing depends on external part Ca, and it in the boost
processing depends on external part Cb. They become longer as the capacity bigger and become shorter as
it gets smaller. (Recommendation value: Ca=1µF, Cb=4.7µF)
Reducing the capacity of Ca may cause the distortion. As for Cb, since it serves as the click noise
prevention, reducing the capacity may cause the click noise upon volume changing.

4. 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.
