NJW1137 P R E L I M I N A LY AUDIO PROCESSOR with SOUND ENHANCEMENT ■ GENERAL DESCRIPTION The NJW1137 is an audio processor with sound enhancement (BBE). 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. The sound enhancement regenerates high definitive and nearly real sound. 2 All of internal status and variables are controlled by I C BUS interface. ■ PACKAGE OUTLINE NJW1137L NJW1137M ■ FEATURES ● Operating Voltage 8 to 13V 2 ● I C BUS Interface ● BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) ● AGC Circuit (It reduces volume difference among input sources.) ● eala(NJRC Original Surround) ● 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 –F NJW1137 ■ 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 2 BBE1a Ach BBE Filter1 (Process) 17 AUX1 Power Supply Pin Auxiliary Output1 3 BBE2a Ach BBE Filter2 (Lo Contour) 18 AUX0 Auxiliary Output0 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 Reference Voltage 7 TONE-La Ach Bass Filter 22 SR-FIL NJRC Original Surround Filter 8 OUTa Ach Output 23 OUTb Bch Output 9 AGC AGC Filter 24 TONE-Lb 10 SS-FIL 11 CVB 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 Bch BBE Filter2 (Process) 14 SCL SCL Data Input (I2C BUS) 29 BBE1b Bch BBE Filter1 (Lo Contour) 15 GND GND 30 INb -2- Bch Input NJW1137 ■ 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.
