随着空间科学技术的发展,空间科学数据的处理任务日益繁重,要求建立一个高速的空间数据网络。高速数据复接器作为空间飞行器下行科学数据的关键设备,其性能对整个空间网络的性能有重要的影响。文章阐述了一种利用现场可编程门阵列FPGA技术设计星载高速复接器的方法,其复接速率超过400Mbit/s。 With the development of space science and technology, the task of processing space science data is becoming more and more burdensome, requiring the establishment of a high-speed spatial data network. As the key equipment for downlinking scientific data of spacecraft, the performance of high-speed data multiplexer has an important impact on the performance of the entire space network. This article describes a method of designing a spaceborne high speed multiplexer using field programmable gate array (FPGA) technology with a multiplexing rate of over 400 Mbit / s.
