NJW1142
PRELIMINARY
AUDIO PROCESSOR
s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJW1142 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 NJW1142 performs eala (NJRC Original Surround) which is regenerated 3D surround sound with only two speakers. 2 All of the internal status and variables are controlled by I C BUS interface. NJW1142M
s FEATURES q Operating Voltage 8 to 10V q Internal 4 Input Audio Selectors and Monitor Output q Low Noise VCA q eala (NJRC Original Surround System) q Simulated Stereo 2 q Variable AGC Compression Level via I C (4-levels) q Bi-CMOS Technology q Package Outline SDMP30
