NJW1164
AUDIO PROCESSOR with BBE
s 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. s PACKAGE OUTLINE

s 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=1F, Cb=4.7F) 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.

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=25uC) Sink current : 0.5mA typ. (Ta=25uC) 6. Capacitor for Reference Voltage (21pin) 22F 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.
