Preliminary Product Brief gm5126

C5126-PBR-01A

the OnPanel LCD monitor market with resolutions up to SXGA.

processing technology as well as a proven integrated ADC/PLL

and an Ultra-Reliable DVI compliant digital receiver to provide

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

a PCB along with its associated connectors and cables. This

reduces system cost, improves reliability and simplifies monitor

Note: resolutions and refresh rates higher than those

in-line inversion, blanking and programmable output

Dual-Interface OnPanel SXGA LCD Controller with RSDS Transmitter

The gm5126 device is an all-in-one image processor targeted on
The gm5126 leverages Genesis patented advanced image-

excellent image quality in simple and cost-effective solution. The

integration reduces the number of components, which eliminates

design.
