Preliminary Product Brief
gm5126
C5126-PBR-01A
The gm5126 device is an all-in-one image processor targeted on
the OnPanel LCD monitor market with resolutions up to SXGA.
The gm5126 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 solution. The
integrated OnPanel timing controller (TCON) is fully
programmable to interface to a wide range of commercially
available LCD panels. A dual channel RSDS (reduced swing
differential signaling) 6 or 8 bit transmitter is provided for direct
connect to column drivers with RSDS inputs. This high level of
integration reduces the number of components, which eliminates
a PCB along with its associated connectors and cables. This
reduces system cost, improves reliability and simplifies monitor
design.
FEATURES
