NJW1130A PPRELIMINARY SOUND PROCESSOR with SOUND ENHANCEMENT ■ GENERAL DESCRIPTION The NJW1130A 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 NJW1130A performs surround and sound enhancement. 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 NJW1130G ■ FEATURES ● Operating Voltage (8 to 13V) 2 ● I C BUS Interface ● BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) ● Internal 6 Input Audio Selectors and Monitor Output ● The AGC circuit reduces volume difference among input sources. ● Matrix Surround ● Bi-CMOS Technology ● Package Outline SOP40 ■ BLOCK DIAGRAM MON a AGC1 BBE BBE 1a 2a PS TONE TONE Ha La OUTa LINEa 4.5dB IN1a CVA CVB IN2a IN3a Input Selector BBE Volume Tone CTH Volume CTL IN4a Control Logic IN5a IN6a Surround AGC AUX0 AUX1 IN1b SDA IN2b IN3b Input Selector IN4b SCL BBE Volume Tone Volume GND IN5b Bias 4.5dB IN6b MON b AGC2 BBE BBE 2b 1b TONE TONE Lb Hb OUTb LINEb VCC Vref Ver.2.0 -1- NJW1130A ■ PIN FUNCTION Ach Input Selector1 1 IN1a IN1b 40 Bch Input Selector1 Ach Input Selector2 2 IN2a IN2b 39 Bch Input Selector2 Ach Input Selector3 3 IN3a IN3b 38 Bch Input Selector3 Ach Input Selector4 4 IN4a IN4b 37 Bch Input Selector4 Ach Input Selector5 5 IN5a IN5b 36 Bch Input Selector5 Ach Input Selector6 6 IN6a IN6b 35 Bch Input Selector6 Ach BBE Filter1 7 BBE1a BBE1b 34 Bch BBE Filter1 Ach BBE Filter2 8 BBE2a BBE2b 33 Bch BBE Filter2 Ach High Frequency 9 TONE-Ha TONE-Hb 32 Bch High Frequency Ach Low Frequency 10 TONE-La TONE-Lb 31 Bch Low Frequency Ach Monitor Output 11 MONa MONb 30 Bch Monitor Output Ach Line Output (4.5dB) 12 LINEa LINEb 29 Bch Line Output(4.5dB) Ach Output (0dB) 13 OUTa OUTb 28 Bch Output(0dB) AGC1 14 AGC1 PS 27 Phase Shift AGC2 15 AGC2 VREF 26 Reference Voltage DAC Output for Bch Volume & Balance 16 CVB CTH 25 DAC Output for Tone High Frequency 17 CVA CTL 24 DAC Output for Tone Low Frequency 2 18 SDA AUX0 23 AUX Output0 I C BUS SCL 2 19 SCL AUX1 22 AUX Output1 GND 20 GND Vcc 21 Power Supply DAC Output for Ach Volume & Balance I C BUS SDA Ver.2.0 -2- NJW1130A ■ 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.
