| 摘 要： | 针对LVDS高速数据传输,本文分析并比较了三种有效的传输方案。结合这些方案的特点和合成孔径雷达成像的需求,本文实现了使用高速时钟采样进行同步接收的LVDS传输方案。该方案有效地解决了在LVDS传输中时钟不连续,没有数传控制信号,和传输数据没有特定帧结构用于数据同步的问题。文中使用FPGA实现了该方案并完成了传输试验。结果表明,该传输系统在3m长的传输距离上可稳定地传输100MBps的数字信号。

| Abstract: | Focusing on LVDS high speed data transmission, weanalyzed and compared three effective transmission schemes. Tocombine these schemes' properties with the need of synthesisaperture radar processing, a high speed clock sampling synchro-nization scheme is implemented. This implementation solves theproblem that there is no continuous sending clock, no datatransmission control signal and no specific data frame structurefor synchronization. A transmission experiments are also finishedvia FPGA based implementation. The results demonstrate thatwith a 3m- long cable, the transmission speed can stably achieve100MBps. |
