LC75106V
CMOS LSI
Digital Echo LSI with Built-in
Mic Amplifier
http://onsemi.com
Overview
The LC75106V is a digital echo LSI for karaoke. It has the microcomputer control mode (I2C BUS control) and non-
control mode. Therefore, various karaoke systems can be made.
This LSI has 2ch mic amplifier (with ALC), volume of 2ch mic, echo feed back volume and echo volume.
In addition, when the stereo signal internal connected mode has the function of the vocal cancellation etc.
The karaoke system can be constructed with this LSI.
Functions
• 2ch mic amplifier (with built-in Auto Level Control)
• Volume of 2ch mic
• With built-in for digital echo memory 32kbit
• Feedback volume for digital echo
• Digital echo volume
• Mic mixing function
• Vocal cancellation
• With built-in oscillation circuit
• I2C bus control
Application
• Mini component audio and other
* I2C Bus is a trademark of Philips Corporation.
