3 General Description

    NCS8801S is a low-power RGB/LVDS-to-DisplayPort/eDP converter, which is designed for mobile devices including smartphones, tablets, laptops, etc. to support high-definition DP/eDP displays.
    NCS8801S supports 4-lane DP/eDP output which is typically required to support QXGA (2048*1536) and above at 60Hz frame rate.
    All the functions including both RGB and LVDS interfaces pack into a small 7mm*7mm QFN56 package which saves the precious space in mobile devices.
