Bi-CMOS IC
LV1117N/NV Surround Processor ICs for
Electronic Volume Control
Overview
The LV1117N/NV are sound processor ICs developed for use in TV sets.
They incorporate the surround processing functions including (AViSS), pseudo stereo function, (L+R) output, and the
major functional blocks of an electronic volume control IC.
Features
• Input function SW (4ch 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]).
• Volume control (0dB to −14dB: 1dB step/−14dB to −80dB: 2dB steps/−∞=−82dB).
• Balance control.
• Through mode/Mute mode.
• Pseudo stereo function (ON/OFF/MONO).
• L+R output with LPF (Mute + 7-stage level control: 8 positions).
• I2C bus control.
• Parallel output ports (4pin).
* Initial gain of L+R AMP can be controlled by the resistance value of external resistor.
