摘　　要：基于当前遥感相机谱段数量的不断增加、分辨率的不断提升等方面造成的数据传输问题,分析了目前广泛应用的并行数据传输系统所面临的技术瓶颈,提出采用串行发送/解串(SerDes)方式加以替代的方案,通过对比分析,指出采用该方式传输数据的优点,进而阐述文章所采用的串行发送/解串芯片-TLK2711的工作原理、传输协议等,最终通过试验证明了其在遥感相机系统中应用的可行性,为后续遥感相机研制提供参考。This article firstly clarifies the problem of data transfer caused by the increasing spectral bands and the heightening resolution for current remote sensing camera, analyses the bottleneck of parallel data transfer system which is widely used, and gives a substitute method-serialization/deserialization（SerDes）. Through comparison and analysis,it points out the strong point of this method, and then illustrates the principles and the transport protocol of the SerDes chip, TLK2711. Finally it gives the conclusion that the design is proved feasible and can be as a reference for later remote sensing camera design.
