摘　　要：为解决高速AD采集项目中PCB布线复杂及多通道数据同步的问题,对基于JESD204B协议的数据传输接口进行了研究。文中利用Xilinx FPGA的GTX高速收发器,实现了基于JESD204B协议的10Gbps数据传输。简述了该系统的架构,详细地阐述了JESD204B链路建立的关键参数配置和数据帧解码的软件设计,并结合Matlab程序对系统的指标进行测试。A 10Gbps data transmission interface based on JESD204B protocol is implemented with Xilinx FPGA GTX transceivers to solve the problem of PCB routing complexity and inter symbol synchronization in AD acquisition. The system architecture is briefly described . The key parameters configuration of JESD204B link establishment and design of data frame and the method of decoding are analyzed in detail, the technical specification is tested by using Matlab.
