LV1117
Bi-CMOS LSI
Surround Processor IC for
Electronic Volume Control
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.
