Product Brief
gm3125
The gm3125 device is an all-in-one image processor targeted on
the "Smart" LCD panel market with resolutions up to SXGA
(1280x1024). The gm3125 leverages Genesis patented
advanced image-processing technology as well a Genesis
proprietary 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.
