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.
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.
