Product Brief gm5221/gm2221
C5221-PBR-01C
September 2003
VGA+DVI+Video Multi-function LCD Monitor Controller
The gm5221 device is an all-in-one LCD monitor controller
• Advanced Color Management
supporting resolutions up to SXGA (1280x1024). The gm5221
leverages Genesis patented advanced image-processing
technology as well as a proven integrated ADC/PLL, an Ultra-
Reliable DVI™ compliant digital receiver, and a CCIR656 video
input port to deliver a high-quality, low cost solution for multi-
function LCD monitors. On-chip, industry standard,
• TV color controls including hue and saturation controls
• Full color matrix allows end-users to experience the same colors as
viewed on CRTs and other displays (e.g. sRGB compliance)
• Advanced Active Color Management ™ (ACM-II) provide flesh-tone
compensation and image enhancement
• Adaptive Contrast and Color™ (ACC) ensures full dynamic range
is used in video content
single/double-pixel, four-channel LVDS 6/8-bit transmitters
connect directly to commercial available LCD panel modules. In
• On-chip OSD Controller
addition, an integrated X86 microcontroller and OSD engine are
• On-chip RAM for high-quality programmable menus
provided. This high level of integration reduces the number of
components. This reduces system cost, improves reliability and
simplifies monitor design.
mgm2221 is a pin-compatible derivative product with integrated
oADC and video input, but no DVI receiver.
