NJRC NJW1165 Audio processor Datasheet

NJW1165
AUDIO PROCESSOR
■ GENERAL DESCRIPTION
The NJW1165 is an audio processor. It includes all of
functions processing audio signal for TV, such as tone
control, balance, volume, mute, NJRC original surround, and
AGC functions.
The NJRC original surround system reproduces natural
surround sound and clear vocal orientation.
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.
