[Genesis Microchip Inc.]

OVERVIEW

The gm5020 is a graphics processing IC providing high-quality images for LCD monitors and other pixelated displays. It combines a triple ADC, the Genesis Ultra-Reliable DVI™ receiver, a high quality zoom and shrink scaling engine, frame rate conversion, an on-screen display (OSD) controller, a microprocessor and many other functions in a single device. This high level of integration enables simple, flexible, cost-effective solutions featuring fewer required components.

The gm5020 is ideal for dual-interface (analog and digital) LCD monitors up to SXGA resolutions.
