VGA+DVI+Video Multi-function LCD Monitor Controller
The gm5221 device is an all-in-one LCD monitor controller
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,
single/double-pixel, four-channel LVDS 6/8-bit transmitters
connect directly to commercial available LCD panel modules. In
addition, an integrated X86 microcontroller and OSD engine are
provided. This high level of integration reduces the number of
components. This reduces system cost, improves reliability and
simplifies monitor design.
gm2221 is a pin-compatible derivative product with integrated
ADC and video input, but no DVI receiver.
