1 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.
1.1 gm2121 System Design Example
Figure 1 below shows a typical dual interface LCD monitor system based on the gm2121. Designs based
on the gm2121 have reduced system cost, simplified hardware and firmware design and increased
reliability because only a minimal number of components are required in the system.
