摘要
介绍了利用现场可编程门阵列FPGA实现低电压差分信号—光纤接口的协议透明、远距离、高速数据传输系统。通过对光纤传输手段的研究,并结合LVDS信号的可靠性,借助现场可编程门阵列的开发灵活性以及锁相环、先入先出存储器等成熟技术,快速的完成了系统的开发。结果表明:这种实现方法简单、快捷、可靠,并且可以方便地实现数据的处理,具有很强的灵活性和可扩展能力。
Based on field programmable gates array（FPGA）, a method of implementing a long-range agreement transparent, highspeed LVDS and optical communication was firstly introduced. By means of optical transmission,combined with LVDS signal reliability, used field programmable gate array flexibility and the development of phase-locked loop, the first-in-first-out memory, the system＇s development was rapidly completed. Some conclusions can be drawn from the experiment such as the facility of the system＇ s builiding, the simpleness and flexibility of the data processing.
