NJW1176 AUDIO PROCESSOR with Subwoofer Output ■ GENERAL DESCRIPTION The NJW1176 is a sound processor with subwoofer output includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1176 includes the LPF for subwoofer output and bass boost function. The 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. ■ PACKAGE OUTLINE ■ FEATURES ● Operating Voltage 7.5 to 13V ● 3ch Output (Lch, Rch, Subwoofer ch) / 2ch Output(Lch, Rch) ● LPF Filter (Adjustable cut off frequency by external parts) ● AGC Circuit (It reduces volume difference among input sources.) 2 Adjustable AGC compression level by I C BUS ● eala(NJRC Original Surround System) ● Simulated Stereo 2 ● I C BUS Interface ● Bi-CMOS Technology ● Package Outline SDIP30, SDMP30, SSOP32 ■ BLOCK DIAGRAM SUR TONETONE TONE SUR - FIL OUTa INa -Ha -La LF1 LF2 LF3 AGC IN a VOL1 IN b TONE VOL1 NJW1176V OUTa SCL SDA VOL2 I2CBUS Interface eala & Simulated Stereo AGC NJW1176M NJW1176L LPF TONE VOL2 CVA CVB CVW CTH CTL Trimmer AUX1 AUX0 VOL2 GND Bias V+ SUR TONE TONE TONE -INb -Hb -Lb OUTb - OUTb OUTw Vref -1- NJW1176 ■PIN CONFIGURATION (SDIP30, SDMP30) No. Symbol 1 INa 2 CVW 3 LF1 4 1 INa INb 30 2 CVW LF2 29 3 LF1 LF3 28 4 SUR OUTa SUR OUTb 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 OUTw 22 10 SUR-FIL VREF 21 11 CVB CTH 20 12 CVA CTL 19 13 SDA AUX0 18 14 SCL AUX1 17 15 GND Vcc 16 Function No Symbol Function Ach Input 16 Vcc Power Supply Pin Wch DAC output terminal for LPF trimmer 17 AUX1 Auxiliary Output1 LPF filter1 terminal 18 AUX0 Auxiliary Output0 SUR OUTa Ach Output for the Other Accessories 19 CTL 5 TONE INa Ach Input From the Other Accessories 20 CTH 6 TONE-Ha Ach Treble Filter 21 VREF 7 TONE-La Ach Bass Filter 22 OUTw Wch Output 8 OUTa Ach Output 23 OUTb Bch Output 9 AGC AGC Filter 24 TONE-Lb Bch Bass Filter 10 SUR-FIL eala and Simulated Stereo Filter 25 TONE-Hb Bch Treble Filter 11 CVB DAC Output for Bch Volume & Balance 26 TONE INb Bch Input from the Other Accessories 12 CVA DAC Output for Ach Volume & Balance 27 SUR OUTb Bch Output for the Other Accessories 13 SDA SDA Data Input (I2C BUS) 28 LF3 14 SCL SCL Data Input (I2C BUS) 29 LF2 LPF filter2terminal 15 GND GND 30 INb Bch Input (✳) -2- DAC Output for Tone Low Frequency DAC Output for Tone High Frequency Reference Voltage LPF filter3 terminal The AUX0 terminal should be connected via the protection resistance to 5V device.
