基于FPGA光纤以太网自协商的设计与实现

his paper analyzed the basic auto-negotiation process of the Gigabit Ethernet, and an implemention model based on the high-speed serial transceivers GTX of Virtex-5 XC5VFX70T has been proposed . This proposal has been implemented by Verilog Coding and downloaded to the Virtex-5 XC5VFX70T evaluation platform to conduct the ARP certification with PC. The results show that, without extra Fiber Ethernet PHY, FPGA board with the program completed the auto-negotiation with the Gigabit Ethernet optical network card and the electronic network card, and achieved data communication with the PC.
