NJW1132A PRELIMINARY AUDIO PROCESSOR with SOUND ENHANCEMENT ■ GENERAL DESCRIPTION The NJW1132A 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 NJW1132A 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. ■ PACKAGE OUTLINE NJW1132AL NJW1132AM ■ FEATURES ● Operating Voltage 8 to 13V ● I2C BUS Interface ● BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) ● AGC Circuit (It reduces volume difference among input sources.) ● Matrix Surround ● Bi-CMOS Technology ● Package Outline SDIP30, SDMP30 ■ BLOCK DIAGRAM BBE BBE BBETONETONE TONE 1a 2a OUTa INa –Ha –La PS AGC1 OUTa CTH CTL Volume 1 IN a BBE Volume 2 Tone CVA CVB Control Logic Surround AGC AUX0 AUX1 SDA SCL Volume 1 IN b BBE Tone Volume 2 GND Bias AGC2 BBE BBE BBETONETONE TONE 1b 2b OUTb INb –Hb –Lb OUTb VCC Vref -1- NJW1132A ■ PIN FUNCTION No. Symbol INb 30 BBE1a BBE1b 29 3 BBE2a BBE2b 28 4 BBEOUTa 5 TONEINa TONEINb 26 6 TONE-Ha TONE-Hb 25 7 TONE-La TONE-Lb 24 8 OUTa OUTb 23 9 AGC1 PS 22 10 AGC2 VREF 21 11 CVB CTH 20 12 CVA CTL 19 13 SDA AUX0 18 14 SCL AUX1 17 15 GND Vcc 16 1 INa 2 Function BBEOUTb No 27 Symbol Function 1 INa Ach Input 16 Vcc Power Supply Pin 2 BBE1a Ach BBE Filter1 17 AUX1 Auxiliary Output1 3 BBE2a Ach BBE Filter2 18 AUX0 4 BBEOUTa Ach BBE Output 19 CTL 5 TONEINa Ach Tone Input 20 CTH 6 TONE-Ha Ach Treble Filter 21 VREF 7 TONE-La Ach Bass Filter 22 PS 8 OUTa Ach Output(0dB) 23 OUTb Auxiliary Output0 DAC Output for Tone Low Frequency DAC Output for Tone High Frequency Reference Voltage Surround Phase Shift Filter Bch Output(0dB) 9 AGC1 AGC1 24 TONE-Lb 10 AGC2 AGC2 25 TONE-Hb Bch Bass Filter Bch Treble Filter 11 CVB DAC Output for Bch Volume & Balance 26 TONEINb Bch Tone Input 12 CVA DAC Output for Ach Volume & Balance 27 BBEOUTb Bch BBE Output 13 SDA SDA Data Input (I2C BUS) 28 BBE2b Bch BBE Filter2 14 SCL SCL Data Input (I2C BUS) 29 BBE1b 15 GND GND 30 INb -2- Bch BBE Filter1 Bch Input NJW1132A ■ 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 ■ELECTRICAL CHARACTERISTICS (Ta=25°C, V+=9V, Rg=600Ω, RL=47kΩ, Vin=100mVrms/1kHz) PARAMETER SYMBOL TEST CONDITION MIN.
