C3110-PBR-01B
Digital-Interface XGA LCD Controller
The gm3110 device is an all-in-one image processor targeted on
LCD monitors with resolutions up to XGA (1024x768). The
gm3110 leverages Genesis patented advanced imageprocessing technology as well a Genesis proprietary UltraReliable DVI-compliant digital receiver to provide excellent
image quality. In addition, an integrated microcontroller is
provided. These features provide a very simple and costeffective solution for high-end, digital interface LCD monitors.
