NJW1147 P R E L I M I N A LY AUDIO PROCESSOR with BBE ViVA ■ GENERAL DESCRIPTION The NJW1147 is a TV audio processor with BBE ViVA High Definition 3D Sound process. BBE's traditional sound clarity enhancement technology is combined with the new ViVA 3D process to create an authentic and exciting spatial effect. BBE ViVA is compatible with news, music and movie programs as well as video games. The NJW1147 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 NJW1147L NJW1147M ■ FEATURES ● Operating Voltage 8 to 13V 2 ● I C BUS Interface ● BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) ● BBE ViVA High Definition 3D Sound ● eala (NJRC Original Surround) ● AGC Circuit (It reduces volume difference among input sources.) ● Simulated Surround ● Bi-CMOS Technology ● Package Outline SDMP30, SDIP30 ■ BLOCK DIAGRAM BBE VOL1 TONE VOL2 ViVA HD3D & eala & Sim ulated Surround AGC VOL1 I2C Bus Interface BBE TONE VOL2 Bias - 1 - NJW1147 ■ PIN FUNCTION No. Symbol 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 1 INa 2 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 4 BBE OUTa Ach Output for the Other Accessories 19 CTL DAC Output for Tone Low Frequency 5 TONE INa Ach Input From the Other Accessories 20 CTH DAC Output for Tone High Frequency 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 AGC Filter 24 TONE-Lb 10 SS-FIL 11 CVB Reference Voltage Bch Bass Filter Simulated Stereo Filter 25 TONE-Hb Bch Treble Filter DAC Output for Bch Volume & Balance 26 TONE INb Bch Input from the Other Accessories Bch Output for the Other Accessories 12 CVA DAC Output for Ach Volume & Balance 27 BBE OUTb 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- Auxiliary Output0 Bch BBE Filter2 (Process) Bch BBE Filter1 (Lo Contour) Bch Input NJW1147 ■ ABSOLUTE MAXIMUM RATING (Ta=25°C) PARAMETER SYMBOL + RATING UNIT 14 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.
