The Genesis gmZAN3 is an all-in-one image processor optimized for conventional LCD monitor designs with resolutions up to XGA. The gmZAN3 leverages Genesis patented advanced image-processing technology as well as a proven integrated ADC to provide excellent image quality in a simple and cost-effective solution. An on-chip, industry standard, single pixel, four channel LVDS 6/8-bit transmitter (gmZAN3-L) provides a direct connection to commercially available LCD panel modules. This high level of integration reduces the number of components, reduces system cost and improves reliability as well as simplifying monitor designs.
