This application note describes the implementation of SERDES Framer Interface Level 5 (SFI-5) [Ref 1] in a Virtex-6 XC6VLX240T FPGA. SFI-5 is a standard defined by the Optical Internetworking Forum (OIF). The interface must operate bidirectionall

V6 FPGA的GTX详细资料，包含了GTX的设计原理和使用方法，适合FPGA代码开发人员。-V6 FPGA GTX detailed information, including the design principle and using method of GTX code, suitable for FPGA developers.

当两块fpga用高速gtx接口transceiver互传数据时出现数据与码不齐时，可以以上方式解决。已使用，没问题。(When two FPGAs use high-speed GTX interface transceiver to transmit data to each other, data and code is not uniform, can be solved in the above way. Yes, no problem.)
