NJW1132 PRELIMINARY SOUND PROCESSOR with SOUND ENHANCEMENT n GENERAL DESCRIPTION The NJW1132 is a sound processor with sound enhancement (BBE). It includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1132 performs surround and sound enhancement. The sound enhancement regenerates high definitive and nearly real sound. All of internal status and variables are controlled by I2C BUS interface. n PACKAGE OUTLINE NJW1132M NJW1132L n FEATURES l Operating Voltage (8 to 13V) lI2C BUS Interface lBBE Sound Enhancement (Low Boost and High Boost: 15dB max.) l The AGC circuit reduces volume difference among input sources. l Matrix Surround l Bi-CMOS Technology l Package Outline SDIP30,SDMP30 n BLOCK DIAGRAM OUTPUT Volume 1 INPUT BBE Volume 2 Tone Control Logic Surround AGC AUX0 AUX1 SDA SCL INPUT Volume 1 BBE Tone Volume 2 GND Bias OUTPUT VCC Vref -1- NJW1132 n PIN FUNCTION INb 30 Bch Input BBE1a BBE1b 29 Bch BBE Filter1 3 BBE2a BBE2b 28 Bch BBE Filter2 Ach BBE Output 4 BBEout_a 27 Bch BBE Output Ach Tone Input 5 Tone_INa Tone_INb 26 Bch Tone Input Ach High Frequency 6 TONE-Ha TONE-Hb 25 Bch High Frequency Ach Low Frequency 7 TONE-La TONE-Lb 24 Bch Low Frequency Ach Output (0dB) 8 OUTa OUTb 23 Bch Output(0dB) AGC1 9 AGC1 PS 22 Phase Shift AGC2 10 AGC2 VREF 21 Reference Voltage DAC Output for Bch Volume & Balance 11 CVB CTH 20 DAC Output for Tone High Frequency DAC Output for Ach Volume & Balance 12 CVA CTL 19 DAC Output for Tone Low Frequency I2C BUS SDA 13 SDA AUX0 18 AUX Output0 I2C BUS SCL 14 SCL AUX1 17 AUX Output1 GND 15 GND Vcc 16 Power Supply Ach Input 1 INa Ach BBE Filter1 2 Ach BBE Filter2 BBEout_b SDIP30, SDMP30 -2- NJW1132 n ABSOLUTE MAXIMUM RATING (Ta=25°C) PARAMETER SYMBOL RATING UNIT Supply Voltage + V 14 V Power Dissipation PD 700 mW Operating Temperature Range Topr -20 to +75 °C Storage Temperature Range Tstg -40 to +125 °C W, Vin=100mVrms/1kHz) n ELECTRICAL CHARACTERISTICS ( Ta=25°C, V+=9V, Rg=600W W, RL=47kW SYM TEST CONDITION MIN.
