摘要
从物理链路与互连协议两个方面进行研究,设计出一种应用串行编解码收发器与现场可编程门阵列(FPGA)器件编程配合,实现遥感卫星设备间数据传输的方案;通过伪随机码传输测试,实现了在速率2Gbit/s下数千亿位无误码的高速稳定串行传输。该设计传输速率快,可靠性高,为高分辨率遥感卫星设备间的数据传输提供了一种解决方案。
Physical Link and serial interconnection protocol are studied. A design of high-speed serial transmission interface for HR（high-resolution） remote sensing satellite is presented, apply- ing serializer/deserializer with FPGA to realize data transmission between equipment. By BER （bit error rate） test, this interface can transfer trillion bit in 2Gbit/s without lbit error. As its characteristic of high transmission speed and high reliability, the design mentioned is one of the solutions to data transmission problem for HR remote sensing satellites.
