NJW1144
AUDIO PROCESSOR
s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJW1144 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 NJW1144 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 NJW1144GK1 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-K1 sBLOCK DIAGRAM

The attenuator is consisted of both the Volume1 and Volume2. 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. 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)
