NJW1130A
PPRELIMINARY
SOUND PROCESSOR with SOUND ENHANCEMENT
s GENERAL DESCRIPTION The NJW1130A is a sound processor with sound enhancement (BBE). It includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1130A performs surround and sound enhancement. The sound enhancement regenerates high definitive and nearly real sound. All of internal status and variables are controlled by I2C BUS interface. s PACKAGE OUTLINE
