NJW1176V

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