NJW1164
AUDIO PROCESSOR with BBE
■ GENERAL DESCRIPTION
The NJW1164 is a TV audio processor with sound
enhancement (BBE).
The NJW1164 contains all necessary functions to process
TV audio signal such as volume control, tone control,
balance, mute, AGC and NJRC's proprietary surround sound
process, eala. The eala reproduces a natural surround
sound with clear vocal orientation.
2
The total modes and variables are controlled by the 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.

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.

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.
