1.1 gm5020 System Design Example
Figure 1 below shows a typical dual interface LCD monitor system based on the gm5020.
Designs based on the gm5020 have reduced system cost and simplified hardware and firmware
design because only a minimal number of components are required in the system. The chip can
be used in a variety of systems, ranging from 'single-chassis' solutions for XGA and SXGA
monitors with frame store memory and video inputs. In addition, the gm5020 can be used in mid-
range SXGA monitors with no frame store memory.
