NJW1140 PRELIMINARY AUDIO PROCESSOR with SRS ■ GENERAL DESCRIPTION The NJW1140 is a sound processor includes all of the functions required to process the audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1140 performs SRS 3D Stereo which regenerates 3D surround sound with only two speakers. All of the internal status and variables are controlled by 2 I C BUS interface. ■ PACKAGE OUTLINE ■ FEATURES ● Operating Voltage 8 to 13V 2 ● I C BUS Interface ● Internal 6 Input Audio Selectors and Monitor Output ● The AGC circuit reduces volume difference among input sources. 2 ● Variable AGC Compression Level via I C (4-levels) ● Includes Dual Surround (SRS 3D Stereo and Simulated Stereo) 2 ● Variable Surround Effect Level via I C (SRS mode, 2-Levels) ● Low Noise VCA ● Bi-CMOS Technology ● Package Outline SOP40 NJW1140GK1 ■ BLOCK DIAGRAM MONa +4.5dB SEL VOL1 TONE SDA VOL2 2 SEL I C BUS Interface SRS 3D Stereo & Sim ulated Stereo AGC VOL1 TONE CTH CTL CSB VOL2 +4.5dB MONb SCL CVA CVB CSR -2dB IN1b IN2b IN3b IN4b IN5b IN6b OUTa -2dB IN1a IN2a IN3a IN4a IN5a IN6a TONE TONE -Ha -La AGC TONETONE -Hb -Lb OUTb Bias GND Vcc Vref - 1 -E NJW1140 ■ PIN CONFIGURATION Ach Input Selector 1 1 IN1a IN1b 40 Bch Input Selector 1 Ach Input Selector 2 2 IN2a IN2b 39 Bch Input Selector 2 Ach Input Selector 3 3 IN3a IN3b 38 Bch Input Selector 3 Ach Input Selector 4 4 IN4a IN4b 37 Bch Input Selector 4 Ach Input Selector 5 5 IN5a IN5b 36 Bch Input Selector 5 Ach Input Selector 6 6 IN6a IN6b 35 Bch Input Selector 6 Ach Monitor Output(-2dB) 7 MONa MONb 34 Bch Monitor Output(-2dB) Surround Filter 1 8 SRS/SS FIL1 SRS FIL2 33 Surround Filter 2 No Connect 9 NC NC 32 No Connect No Connect 10 NC NC 31 No Connect Ach Tone High Frequency 11 TONE-Ha TONE-Hb 30 Bch Tone High Frequency Ach Tone Low Frequency 12 TONE-La TONE-Lb 29 Bch Tone Low Frequency Ach Line Output (4.5dB) 13 LINEa LINEb 28 Bch Line Output (4.5dB) Ach Main Output (0dB) 14 OUTa OUTb 27 Bch Main Output (0dB) 15 AGC CSR 26 DAC Output for Surround ON/OFF DAC Output for Ach Volume & Balance 16 CVa CTH 25 DAC Output for Tone High Frequency DAC Output for Bch Volume & Balance 17 CVb CTL 24 DAC Output for Tone Low Frequency I2C Bus SDA 18 SDA NC 23 No Connect I2C Bus SCL 19 SCL Vref 22 Reference Voltage 20 GND V+ 21 Power Supply AGC GND - 2- NJW1140 ■ ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER SYMBOL + RATING UNIT 15 V Supply Voltage 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.

The total attenuation level is summing of each attenuation level of the Volume1 and Volume2. The attenuation for both the Volume1 and Volume2 are always synchronized to have the same attenuation levels for each other, and are not controllable independently for each other. •”VOL” : Sets the total attenuation level for the both Ach and Bch(up to 84dB, 0.33dB/step) ●CHANNEL BALANCE AND SURROUND MODE CONTROL BIT Select Address D7 01H CHS D6 D5 D4 BAL D3 D2 D1 D0 SR1 SR0 ◆Channel Balance Control To control the balance between Ach and Bch, the both commands “CHS” and “BAL” should be set. For example, to move a sound image to Ach-side, Bch should be attenuated with no attenuation on Ach. The command “CHS” defines the channel should be attenuate, and the command “BAL” defines the attenuation level itself. The attenuation for the balance control is consisted of the both Volume1 and Volume2, has the same structure with Master Volume Control described above. •”CHS” : Defines the channel should be attenuated The channel CHS should be attenuated (D7) Bch 0 Ach 1 •”BAL” : Defines the attenuation level for the specified channel with command “CHS”(up to 30dB, 1dB/Step) ◆Surround Mode Control •”SR1”, “SR0” : Surround Mode Switch -
