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.

1) The explanation of I2C Bus
I2C Bus (Inter IC Bus) is the bus system which the PHILIPS company developed.
It does controls such as the start, the stop by two control signals of SDA (Serial Data) and SCL (Serial Clock).
The output of each signal is open drain and forms out of wired OR.
S: Start condition
P: Stop condition
ACK: Acknowledge
Data is transmitted in the MSB first. 1 unit is composed of 8 bits and ACK is put back from the slave to confirm.
Slave IC reads data with rising edge of SCL. Master IC changes data by falling edge in SCL.
2) The control register

Note; LV1117N/NV are reception exclusive use. It depends and it uses LSB by the "0" fixation.
