Overview
The gm2121 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at 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, an on-chip micro-controller (OCM) and industry standard dual four channel LVDS transmitter for direct connect to LCD panels with LVDS interface. With this level of integration, the gm2121 devices simplify and reduce the cost of LCD monitors while maintaining a high degree of flexibility and quality.
