AIT1168 Description

    The AIT1168 is a single-chip VGA-to-Video scan converter for integration into computer-based applications which are designed to be synchronous to the TV at 2X the frame rate and line rate of the TV. The AIT1168 is a pin-compatible upgrade from the AIT1108, providing additional features and improved image processing capability, including hardware scaling of computer images for TV-size underscan display. The Block Diagram shows all the functions in the fully-integrated digital scan converter, providing complete system features for stand-alone use without an external microcontroller. The advanced Flic-Free™ digital filter technology produces outstanding video quality for a clear and stable display.

Advanced Flic-Free™ Digital Filter Technology

    The Flic-Free™anti-flicker filter is a fully-digital adaptive flicker filter derived from AITech's experience in providing high quality scan converter modules as system peripheral products. It provides the user with 3 different filter levels. It also provides a built-in color bar test pattern which may be useful in component or system testing or in video system set-up.
