摘　　要：针对目前我国空间探测任务中海量数据传输的迫切需求,提出了一种星载高速数据传输技术的解决方案。论述了方案的总体设计结构和关键模块的实现,制定了一种可靠易实现的链路传输协议,并给出了收发方向上的后仿真波形。系统联试验证了4通道点对点之间的Ser Des接口数据传输速率达到了2.4Gbps,并且具有很好的带宽扩展和抗干扰性能。在星上有效载荷数据传输系统中具有广阔的应用前景。This paper proposed a high speed on-board data transmission solution to meet the demands of the space data transmission. The whole design structure and the key module were illustrated. A reliable and easily implemented link proto-col was designed. Post simulation waveform along the receiving and sending direction was demonstrated. System test proved that the data transmission rate for 4 channel point to point SerDes interface could reach 2. 4Gbps. Besides, the system had good performance in band width extension and disturb-resistance, which showed promising applications in the on-board payload data transmission area.
