NJRC NJW1168L Audio processor with input selector and subwoofer output Datasheet

PRELIMINARY
NJW1168
AUDIO PROCESSOR with Input Selector and Subwoofer Output
■ GENERAL DESCRIPTION
The NJW1168 is a sound processor with subwoofer
output includes all of functions processing audio signal for
TV, such as input selector, tone control, balance, volume,
mute, and AGC functions.
Also the NJW1168 includes the LPF for subwoofer output
and bass boost function.
The eala reproduces a natural surround sound with clear
vocal orientation. And also, voice enhancement gives clear
sound such as dialogs.

All of internal status and variables are controlled by I C
BUS interface.

The NJW1168 includes the LPF for subwoofer output and bass boost function. The LPF consists of primary and
secondary LPF and it is enable to adjust “cut off frequency”, “Q” and “Roll off”.
The expression of LPF characteristics is as follows.
