NJW1145 AUDIO PROCESSOR ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE The NJW1145 is a audio processor with sound enhancement (BBE). It includes all of the functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1145 performs surround and sound enhancement. The sound enhancement regenerates high definitive and nearly real sound. All of the internal status and variables are controlled by 2 NJW1145GK1 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) ● NJRC Surround "eala" and Simulated Surround 2 ● Variable Surround Effect Level via I C ● Low Noise VCA ● Bi-CMOS Technology ● Package Outline SOP40-K1 ■ BLOCK DIAGRAM MONa +4.5dB SDA SCL SEL VOL1 SEL BBE TONE VOL2 VOL1 BBE TONE VOL2 +4.5dB -2dB MONb CVA CVB CTH CTL CSR CSB I2C BUS Interface NJRC Surrond “eala” & Sim ulated Stereo AGC IN1b IN2b IN3b IN4b IN5b IN6b OUTa -2dB IN1a IN2a IN3a IN4a IN5a IN6a TONE TONE -Ha -La AGC TONE TONE -Hb -Lb OUTb GND Vcc Bias Vref -1- NJW1145 ■ PIN CONFIGURATION 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 (-2dB) 7 MONa MONb 34 Bch Monitor Output terminal (-2dB) Surround Filter 1 8 SS FIL1 SR 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 TONE-Ha TONE-Hb 30 Bch Treble Filter TONE-Lb 29 Bch Bass Filter Ach Treble Filter 11 -2- Ach Bass Filter 12 TONE-La Ach Line Output Terminal (4.5dB) 13 LINEa LINEb 28 Bch Line Output Terminal (4.5dB) Ach Output Terminal (0dB) 14 OUTa OUTb 27 Bch Output Terminal (0dB) AGC Filter 15 AGC CSR 26 Pop Noise Reduction Filter for Surround ON/OFF Control Pop Noise Reduction Filter f or Ach Volume & Balance 16 CVa CTH 25 Pop Noise Reduction Filter f or Treble Control Pop Noise Reduction Filter f or Bch Volume & Balance 17 CVb CTL 24 Pop Noise Reduction Filter f or Bass Control I2C Bus Data Input 18 SDA CSB 23 Pop Noise Reduction Filter for BBE ON/OFF Control I2C Bus Clock Input 19 SCL Vref 22 Ref erence Voltage Terminal GND Terminal 20 GND 21 Pow er Supply Terminal V+ NJW1145 ■ 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. 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 - 12 - Surround Mode SR1 (D1) SR0 (D0) Surround OFF (Bypass) 0 0 Simulated Surround 0 1 3D Surround – High Mode 1 0 3D Surround – Low Mode 1 1 NJW1145 ●BASS-TONE CONTROL SETTING BIT Select Address D7 02H BCB D6 D5 D4 D3 BASS D2 D1 BCSB D0 SUB-BASS •”BCB”: Defines the Bass-Tone Control Mode as Boost or Cut Bass Tone Control Mode BCB (D7) Cut 0 Boost 1 •”BASS”: Sets the Cut or Boost level for Bass-Tone Control (up to 15dB, 1dB/Step) •”BCSB”: Defines the Sub-Bass-Tone Control Mode as Boost or Cut Sub-Bass Tone Control Mode BCSB (D2) Cut 0 Boost 1 •”SUB-BASS”: Sets the Cut or Boost level for Sub-Bass-Tone Control (up to 3dB, 1dB/Step) ●TREBLE-TONE CONTROL SETTING BIT Select Address D7 03H BCT D6 D5 D4 D3 TREB D2 D1 BCST D0 SUB-TREB •”BCT”: Defines the Treble-Tone Control Mode as Boost or Cut Treble-Tone Control Mode BCT (D7) Cut 0 Boost 1 •”TREB”: Sets the Cut or Boost level for Treble-Tone Control (up to 15dB, 1dB/Step) •”BCST”: Defines the Sub-Treble-Tone Control Mode as Boost or Cut Sub-Treble-Tone Control Mode BCST (D2) Cut 0 Boost 1 •”SUB-TREB”: Sets the Cut or Boost level for Sub-Treble-Tone Control (up to 3dB, 1dB/Step) ●BBE BOOST LEVEL SETTING Select Address 04H BIT D7 D6 D5 D4 D3 D2 BBE-Low D1 D0 BBE-High The command “BBE-Low” and “BBE-High” can set the only BBE boost level, not BBE ON/OFF control. To activate the BBE, the command “BBE” (Address=05H) must be ON. •”BBE-Low”: Sets the BBE low frequency boost level (up to 15dB, 1dB/Step) •”BBE-High”: Sets the BBE high frequency boost level (up to 15dB, 1dB/Step) -
