NJW1172 AUDIO PROCESSOR ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE The NJW1172 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 NJW1172 performs BBE sound enhancement and SRS 3D Stereo. The BBE regenerates high definitive and nearly real sound, and SRS 3D Stereo regenerates 3D surround sound with only two speakers. All of the internal status and variables are controlled by 2 NJW1172GK1 I C BUS interface. ■ 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. 2 ● Variable AGC Compression Level via I C (4-levels) ● SRS 3D Stereo and Simulated Stereo 2 ● Variable Surround Effect Level via I C ● Low Noise VCA ● Bi-CMOS Technology ● Package Outline SOP40-K1 ■BLOCK DIAGRAM MONa IN1a IN2a IN3a IN4a IN5a IN6a VCAINa TONE TONE -La -Ha AGC SDA SCL SEL VOL1 SEL BBE TONE VOL2 I2C BUS Interface SRS 3D Stereo & Sim ulated Stereo AGC IN1b IN2b IN3b IN4b IN5b IN6b OUTa VOL1 BBE TONE VOL2 Bias MONb VCAINb TONE TONE -Hb -Lb CVA CVB CTH CTL CSR CSB OUTb Vref -1- GND Vcc NJW1172 ■ PIN CONFIGURATION - 2- Ach Input Terminal 1 1 IN1a IN1b 40 Bch Input Terminal 1 Ach Input Terminal 2 2 IN2a IN2b 39 Bch Input Terminal 2 Ach Input Terminal 3 3 IN3a IN3b 38 Bch Input Terminal 3 Ach Input Terminal 4 4 IN4a IN4b 37 Bch Input Terminal 4 Ach Input Terminal 5 5 IN5a IN5b 36 Bch Input Terminal 5 Ach Input Terminal 6 6 IN6a IN6b 35 Bch Input Terminal 6 Ach Monitor Output Terminal 7 MONa MONb 34 Bch Monitor Output Terminal Surround Filter 1 8 SRS/SS FIL1 SRS FIL2 33 Surround Filter 2 Ach BBE Filter 1 9 BBE1a BBE1b 32 Bch BBE Filter 1 Ach BBE Filter 2 10 BBE2a BBE2b 31 Bch BBE Filter 2 Ach Treble Filter 11 TONE-Ha TONE-Hb 30 Bch Treble Filter Ach Bass Filter 12 TONE-La TONE-Lb 29 Bch Bass Filter Ach VCA Input Terminal 13 V CAINa VCA INb 28 Bch V CA Input Terminal Ach Output Terminal (0dB) 14 OUTa OUTb 27 Bch Output Terminal (0dB) AGC Filter 15 A GC CSR 26 Pop Noise Reduction Filter f or Surround ON/OFF Control Pop Noise Reduction Filter f or Ach V olume & Balance 16 CV a CTH 25 Pop Noise Reduction Filter f or Treble Control Pop Noise Reduction Filter f or Bch V olume & Balance 17 CV b CTL 24 Pop Noise Reduction Filter f or Bass Control I2 C Bus Data Input 18 SDA CSB 23 Pop Noise Reduction Filter f or BBE ON/OFF Control I2C Bus Clock Input 19 SCL V ref 22 Ref erence Voltage Terminal GND Terminal 20 GND 21 Pow er Supply Terminal V+ NJW1172 ■ 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.

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.
