随着高分辨率卫星载荷CCD相机的分辨率越来越高,其获取的图像数据量急剧增加,如何将载荷数据高速可靠地传输至后端设备处理是必须解决的问题。本文在高速串行接口芯片TLK2711和同源时钟的基础上进行研究,针对星载TLK2711在高速数传链路中可能出现的传输误码等问题进行分析,提出了一种基于低复杂度CRC算法的高速数传接口设计,分别从硬件和逻辑两个方面进行高速数传的可靠性分析。硬件方面基于同源时钟,在发送端和接收端对FPGA和TLK2711提供参考时钟,逻辑方面通过FB-SC-CRC校验方法,在高速传输时为数据提供数据监测、少错纠正的技术保障,降低了数据传输时的资源消耗。经试验验证,通过使用同源时钟,该数传接口实现了可靠的数据传输,码率可达1600 Mbit/s,误码率约为0,逻辑资源使用比传统CRC降低了约2/3。

Currently, the electrochemical CO_(2) reduction reaction (CO_(2) RR) can realize the resource conversion of CO_(2) , which is a promising approach to carbon resource use. Important advancements have been made in exploring the CO_(2) RR performance and mechanism because of the rational design of electrolyzer systems, such as H-cells, flow cells, and catalysts. Considering the future development direction of this technology and large-scale application needs, membrane electrode assembly (MEA) systems can improve energy use efficiency and achieve large-scale CO_(2) conversion, which is considered the most promising technology for industrial applications. This review will concentrate on the research progress and present situation of the MEA component structure. This paper begins with the composition and construction of a gas diff usion electrode. Then, the application of ion-exchange membranes in MEA is introduced. Furthermore, the eff ects of pH and the anion and cation of the anolyte on MEA performance are explored. Additionally, we present the anode reaction type in MEA. Finally, the challenges in this field are summarized, and upcoming trends are projected. This review should offer researchers a clearer picture of MEA systems and provide important, timely, and valuable insights into rational electrolyzer design to facilitate further development of CO_(2) electrochemical reduction.
