Product Brief
gm5125
The gm5125 device is an all-in-one image processor targeted on
the "Smart" LCD panel market with resolutions up to SXGA
(1280x1024). The gm5125 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 in simple and cost-
effective solutions. The integrated OnPanel timing controller
(TCON) is fully programmable to interface to a wide range of
commercially available LCD panels. In addition, an integrated
microcontroller is provided. This high level of integration reduces
the number of components by eliminating the need for an LCD
controller PCB and its associated connectors and cables. This
reduces system cost, improves reliability and simplifies monitor
design.
