AIT2139

The AIT2139 is a single-chip analog RGB in, multi-sync Video Signal Processor which can operate in asynchronous multi-sync modes with an external memory. The multi-sync capability makes it ideal for TV or other applications which are designed to be stand alone without any software required. The AIT2139 complies with the Macrovision* tape copy protection. The Block Diagram shows all the functions in the fully-integrated scan converter, providing complete system features for stand-alone use without an external microcontroller. The advanced Flic-Free™ digital filter technology and improved signal processing produce outstanding video quality for a clear and stable display of graphics and text.
