LV1117

www.DataSheet.co.kr Ordering number : ENN*8264 Bi-CMOS LSI LV1117 Overview Surround Processor IC for Electronic Volume Control 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.
