92706 / 31005 YY PC No.8264-1/3
LV1117
Overview
The LV1117 is a sound processor IC developed for use in TV sets.
It incorporates surround processing function (AViSS
), pseudo stereo function, auto gain control, and the major functional
blocks of an electronic volume control IC.
Functions
Input function SW (4-channel stereo inputs [L, R] )
LINE OUT (through output)
Input gain control (-6dB, -4dB, 0dB, 4dB, 6dB: 5 positions)
AViSS
(ON/OFF/6-stage level control)
Tone control (BASS: ±20dB, TREBLE: ±18dB [in 2dB steps])
Master volume control (0dB to -14dB: 1dB steps/-14dB to -80dB: 2dB steps/-∞ = -82dB)
Balance control
THROUGH mode/MUTE mode
Pseudo stereo function (ON/OFF/MONO control)
L+R output with LPF (MUTE + 7-stage level control: 8 positions)
I2C bus control
Parallel output port (4 pin)
* Initial output gain of L+R can be controlled by the resistance value of external resistor.
