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 inmobile devices.
