3 General Description
NCS8805 is a low-power RGB/LVDS-to-DisplayPort/eDP converter with advanced scaling function, fractional scaling ratio from 2:1 to 1:2, which is designed for mobile devices including tablets, laptops, monitor, etc. to support high-definition DP/eDP displays.
NCS8805 supports 4-lane DP/eDP output which is typically required to support QXGA(2048*1536) and above at 60Hz frame rate.
Thanks to our proprietary scaling algorithm, NCS8805 provides high picture quality. All the functions including both RGB and LVDS interfaces pack into a small 7mm*7mmQFN56 package which saves the precious space in mobile devices.
