PRELIMINARY 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. ■ PACKAGE OUTLINE NJW1164L NJW1164M ■ FEATURES ● Operating Voltage 7.5 to 13V 2 ● I C BUS Interface ● BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) ● eala (NJRC Original Surround) ● AGC Circuit (It reduces volume difference among input sources.) ● Simulated Surround ● Bi-CMOS Technology ● Package Outline SDIP30, SDMP30 ■ BLOCK DIAGRAM VOL1 BBE TONE VOL2 I2C Bus Interface eala & Sim ulated Surround AGC VOL1 BBE TONE VOL2 Bias - 1 - NJW1164 PRELIMINARY ■ PIN FUNCTION No. Symbol 1 INa 2 INb 30 BBE1a BBE1b 29 3 BBE2a BBE2b 28 4 BBEOUTa BBEOUTb 27 5 TONE INa TONE INb 26 6 TONE-Ha TONE-Hb 25 7 TONE-La TONE-Lb 24 8 OUTa OUTb 23 9 AGC SR-FIL 22 VREF 21 10 SS-FIL 11 CVB CTH 20 12 CVA CTL 19 13 SDA AUX0 18 14 SCL AUX1 17 15 GND Vcc 16 Function No Symbol Function 1 INa Ach Input 16 Vcc Power Supply Pin 2 BBE1a Ach BBE Filter1 (Process) 17 AUX1 Auxiliary Output1 3 BBE2a Ach BBE Filter2 (Lo Contour) 18 AUX0 Auxiliary Output0 4 BBE OUTa Ach Output for the Other Accessories 19 CTL Pop Noise reduction for Bass Control 5 TONE INa Ach Input From the Other Accessories 20 CTH Pop Noise reduction for Treble Control 6 TONE-Ha Ach Treble Filter 21 VREF 7 TONE-La Ach Bass Filter 22 SR-FIL Surround Filter 8 OUTa Ach Output 23 OUTb Bch Output 9 AGC 10 SS-FIL Reference Voltage AGC Filter 24 TONE-Lb Bch Bass Filter Simulated Stereo Filter 25 TONE-Hb Bch Treble Filter 11 CVB Pop Noise Reduction for Volume & Balance 26 TONE INb Bch Input from the Other Accessories 12 CVA Pop Noise Reduction for Volume & Balance 27 BBE OUTb Bch Output for the Other Accessories 13 SDA SDA Data Input (I2C BUS) 28 BBE2b 2 14 SCL SCL Data Input (I C BUS) 29 BBE1b 15 GND GND 30 INb -2- Bch BBE Filter2 (Process) Bch BBE Filter1 (Lo Contour) Bch Input PRELIMINARY NJW1164 ■ ABSOLUTE MAXIMUM RATING (Ta=25°C) PARAMETER SYMBOL + RATING UNIT 15 V Supply Voltage V Power Dissipation PD 700 mW Operating Temperature Range Topr -20 to +75 °C Storage Temperature Range Tstg -40 to +125 °C ■ ELECTRICAL CHARACTERISTICS (Ta=25°C, V+=9V, Rg=600Ω, RL=47kΩ, Vin=100mVrms/1kHz unless otherwise specified) PARAMETER SYMBOL TEST CONDITION + MIN.

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.

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. - 10 - PRELIMINARY NJW1164 2.
