ZAN3
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.
FEATURES
