OVERVIEW
The gm2110/20 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA resolution. It provides all key IC functions required for the highest quality LCD monitors. On-chip functions include a high-speed triple-ADC and PLL, a high quality zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and an on chip microcontroller (OCM). With this level of integration, the gm2110/20 devices simplify and reduce the cost of LCD monitors while maintaining a high-degree of flexibility and quality.
