NJRC NJW1132L Sound processor with sound enhancement Datasheet

NJW1132
PRELIMINARY
SOUND PROCESSOR with SOUND ENHANCEMENT
n GENERAL DESCRIPTION
The NJW1132 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 NJW1132 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.
