LV1116N/NV
Overview
Surround Processor ICs for
Electronic Volume Control
The LV1116N/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 SWs (stereo inputs [L, R]). • Line out pin (through output). • Input gain control (−6dB, −4dB, 0dB, 4dB, 6dB: 5 positions). • AViSS (ON/OFF/4-stage level control). • Tone control (BASS: ±20dB, TREBLE: ±18dB [in 2dB steps]). • 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). • L+R output with LPF (Mute + 7-stage level control: 8 positions). • I2C bus control. * Initial gain of L+R AMP can be controlled by the resistance value of external resistor.

I2C BUS register
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 Table1 Slave Address

Tone Circuit Constant Calculation Examples
Treble Band Circuit: The shelving characteristics can be obtained for the treble band. The equivalent circuit and calculation formula during boost are indicated below. • Calculation example 1 Specification Set frequency: f = 10000Hz Gain during maximum boost: G+18dB = 17.5dB Let us use R1 = 6.51kΩ and R2 = 45.19kΩ The above constants are inserted in the following formula G = 20 × Log10 1+ R2 R12+(1/ ω C)2 1 C= 2πf R2 10G/20-1

Bass Band Circuit: The equivalent circuit and the formula for calculating the external RC with a mean frequency of 100Hz are shown below. • Calculation example 1 specification Mean frequency: f0 = 100Hz Gain during maximum boost: G+20dB = 20dB Let us use R1 = 0kΩ and R2 = 66.7kΩ, and C1 = C2 = C. We obtain R3 from G = 20dB G = 20 × Log10 1+ R2 2 (10G+20dB/20 - 1) R2 2R3 = 66700 2 (10 - 1) ≈3.6kΩ

Note item when using (1) When turning on the power, the setting inside is unsettled. Before setting control data, it does a mute. (2) To prevent the digital noise of the high frequency influence a terminal. (SCL, SDA) It can be protected by a signal line in the ground pattern or by the shielding cable. (3) To prevent the noise in changing a mode, please set the mute ON.
