GENESIS GM5221 LCD TV CONTROLLER
The gm5221 is an LCD TV controller supporting resolutions up to SXGA (1280x1024). The gm5221
leverages Genesis patented advanced image-processing technology as well as a proven integrated
ADC/PLL and an Ultra-Reliable DVI™ compliant digital receiver to provide excellent image quality.
gm5221 also integrates a microcontroller, an OSD controller, advanced color management and dual
LVDS transmitters.
1.1 gm5221 System Design Example
Figure 1 below shows a typical dual interface LCD TV system based on the gm5221. Designs based on
the gm5221 have reduced system cost, simplified hardware and firmware design and increased reliability
because only a minimal number of components are required in the system.
