NJW1172 AUDIO PROCESSOR s GENERAL DESCRIPTION s 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 NJW1172GK1 2 I C BUS interface. s FEATURES qOperating Voltage 8 to 13V 2 q I C BUS Interface q BBE Sound Enhancement (Low Boost and High Boost: 15dB max.) q Internal 6 Input Audio Selectors and Monitor Output q The AGC circuit reduces volume difference among input sources. 2 q Variable AGC Compression Level via I C (4-levels) q SRS 3D Stereo and Simulated Stereo 2 q Variable Surround Effect Level via I C q Low Noise VCA q Bi-CMOS Technology q Package Outline SOP40 sBLOCK DIAGRAM MONa VCAINa AGC TONE TONE -La -Ha OUTa IN1a IN2a IN3a IN4a IN5a IN6a SDA SCL SEL VOL1 SRS 3D Stereo & Sim ulated Stereo VOL1 BBE TONE VOL2 Bias GND Vcc BBE TONE VOL2 I2C BUS Interface AGC IN1b IN2b IN3b IN4b IN5b IN6b CVA CVB CTH CTL CSR CSB SEL MONb VCAINb TONE TONE -Hb -Lb OUTb Vref -1- NJW1172 s PIN CONFIGURATION Ach Input Terminal 1 Ach Input Terminal 2 Ach Input Terminal 3 Ach Input Terminal 4 Ach Input Terminal 5 Ach Input Terminal 6 Ach Monitor Output Terminal Surround Filter 1 Ach BBE Filter 1 Ach BBE Filter 2 Ach Treble Filter Ach Bass Filter Ach VCA Input Terminal Ach Output Terminal (0dB) AGC Filter Pop Noise Reduction Filter f or Ach V olume & Balance Pop Noise Reduction Filter f or Bch V olume & Balance I2 C Bus Data Input I2C Bus Clock Input GND Terminal 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 IN1a IN2a IN3a IN4a IN5a IN6a MONa SRS/SS FIL1 BBE1a BBE2a TONE-Ha TONE-La V CAINa OUTa A GC CV a CV b SDA SCL GND IN1b IN2b IN3b IN4b IN5b IN6b MONb SRS FIL2 BBE1b BBE2b TONE-Hb TONE-Lb VCA INb OUTb CSR CTH CTL CSB V ref V+ 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 Bch Input Terminal 1 Bch Input Terminal 2 Bch Input Terminal 3 Bch Input Terminal 4 Bch Input Terminal 5 Bch Input Terminal 6 Bch Monitor Output Terminal Surround Filter 2 Bch BBE Filter 1 Bch BBE Filter 2 Bch Treble Filter Bch Bass Filter Bch V CA Input Terminal Bch Output Terminal (0dB) Pop Noise Reduction Filter f or Surround ON/OFF Control Pop Noise Reduction Filter f or Treble Control Pop Noise Reduction Filter f or Bass Control Pop Noise Reduction Filter f or BBE ON/OFF Control Ref erence Voltage Terminal Pow er Supply Terminal - 2- NJW1172 s ABSOLUTE MAXIMUM RATING (Ta=25C) PARAMETER SYMBOL Supply Voltage Power Dissipation Operating Temperature Range Storage Temperature Range V + RATING 14 700 -20 to +75 -40 to +125 UNIT V mW C C PD Topr Tstg s ELECTRICAL CHARACTERISTICS ( Ta=25C, V =9V, Rg=600, RL=47k, Vin=100mVrms/1kHz) PARAMETER Operating Voltage Supply Current Reference Voltage Maximum Input Voltage Maximum Output Voltage MON OUT Gain Maximum Gain Minimum Gain Channel Balance Balance Level A-A Balance Level A-B Balance Level B-B Balance Level B-A Total Harmonic Distortion Input Selector Cross Talk Channel Separation Output Noise 1 Output Noise 2 SYMBOL V + + TEST CONDITION No Signal No Signal IN1a-6a/IN1b-6b VOL=-20dB, THD=10% OUTa/OUTb VOL=0dB, THD=3% MON OUT VOL=0dB VOL=Mute, Vin=1Vrms BW=400Hz to 30kHz VOL=0dB Full panning to Ach, OUTa Full panning to Ach, OUTb Vin=1Vrms BW=400Hz to 30kHz Full panning to Bch, OUTb Full panning to Bch, OUTa Vin=1Vrms BW=400Hz to 30kHz Vo=0.5Vrms BW=400Hz to 30kHz Vin=1Vrms BW=400Hz to 30kHz Vin=1Vrms BW=400Hz to 30kHz VOL=0dB BW=400Hz to 30kHz VOL=Mute BW=400Hz to 30kHz MIN. 8.0 4.0 2.8 2.0 -2.0 -1.5 -2.0 -2.0 - TYP. 9.0 13 4.5 3.0 2.5 0.0 0.0 0.0 0.0 0.0 -90 (31.6) -106 (5.0) MAX. 13.0 25 5.0 2.0 -70 1.5 2.0 -70 2.0 -70 0.5 -70 -70 -85 (56.2) -96 (15.8) UNIT V mA V Vrms Vrms dB dB dB dB dB dB dB dB % dB dB dBV (Vrms) dBV (Vrms) ICC VREF VIM VOM GVMON GVMAX GVMIN GCB BALAA BALAB BALBB BALBA THD CT CS VNO1 VNO2 -3- NJW1172 s ELECTRICAL CHARACTERISTICS ( Ta=25C, V =9V, Rg=600, RL=47k, Vin=100mVrms/1kHz) q TONE CONTROL (Tone Control-ON) PARAMETER High Frequency Boost High Frequency Flat High Frequency Cut Low Frequency Boost Low Frequency Flat Low Frequency Cut SYMBOL HFBST HFFLT HFCUT LFBST LFFLT LFCUT TEST CONDITION TREBLE=+15dB, f=10kHz TRBE=0dB, f=10kHz TREBLE=-15dB, f=10kHz BASS=+15dB, f=100Hz BASS=0dB, f=100Hz BASS=-15dB, f=100Hz MIN. 12.5 -2.0 -17.5 12.5 -2.0 -17.5 TYP. 15.0 0.0 -15.0 15.0 0.0 -15.0 MAX. 17.5 2.0 -12.5 17.5 2.0 -12.5 UNIT dB dB dB dB dB dB + q SUB-TONE CONTROL (Sub-Tone Control-ON) PARAMETER High Frequency Boost High Frequency Flat High Frequency Cut Low Frequency Boost Low Frequency Flat Low Frequency Cut q AGC (AGC-ON) PARAMETER AGC BOOST AGC FLAT 1 AGC FLAT 2 AGC FLAT 3 AGC FLAT 4 AGC CUT q BBE (BBE-ON) PARAMETER BBE Low Frequency Boost Level BBE High Frequency Boost Level SYMBOL BBELOW BBEHIGH TEST CONDITION BBE-Low=+15dB BBE-High=+15dB 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) qCHANNEL BALANCE AND SURROUND MODE CONTROL Select Address 01H BIT D7 CHS D6 D5 D4 BAL D3 D2 D1 SR1 D0 SR0 xChannel 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.
