国产首款HDMI转DP/EDP（CS5801替RTD2556）性价比高

国产首款HDMI转DP/EDP(CS5801替换RTD2556)，技术支持，性价比超高
HDMI2.0b to DisplayPort1.4 converter
DP接口(DisplayPort)是一种图像显示接口，它不仅可以支持全高清显示分辨率(1920×1080)，还能支持4k分辨率(3840×2160)，以及最新的8k分辨率(7680×4320)。DP接口不仅传输率高，而且可靠稳定，其接口传输的信号由传输图像的数据通道信号以及传输图像相关的状态、控制信息的辅助通道信号组成，具体包含DisplayPort数据传输主要通道(Main Link)、辅助通道(AUX Channel)与连接(Link Training)。
高清晰度多媒体接口(英文:High Definition Multimedia Interface，HDMI)是一种数字化视频/音频接口技术，是适合影像传输的专用型数字化接口，其可同时传送音频和影像信号，最高数据传输速度为2.25GB/s，同时无需在信号传送前进行数/模或者模/数转换。

The CS5801 is a HDMI2.0b to DP1.4a converter. CS5801 has a HDMI2.0b input and the maximum bandwidth is 
up to 18Gbps. It supports the highest resolutions of 4k@60Hz. For DP1.4 output, it consists of 4 data lanes, 
supporting 1.62Gbps, 2.7Gbps, 5.4Gbps link rate. The build-in optional SSC function reduces EMI effect. 
The embedded MCU is based on a 32-bit RISC-V core with internal serial flash. 
The CS5801 is suitable for multiple market segments and display applications, such as monitor, Dongles, Mobile 
systems, and embedded applications.
