3 General Description

    NCS8803 is a low-power HDMI-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.
    NCS8803 supports 4-lane DP/eDP output which is typically required to support WQXGA(2560*1600) and above at 60Hz frame rate.
    NCS8803 Minimum support to XGA (1024*768@60Hz) fail safe mode.
    Thanks to our proprietary scaling algorithm, NCS8803 provides high picture quality. All the
functions pack into a small 7mm*7mmQFN56 package which saves the precious space in
mobile devices.
