摘要: 为解决AD采集项目中PCB布线复杂及码间同步的问题,对基于JESD204B协议的数据传输接口进行了研究。文中利用Xilinx Kintex-7 FPGA的GTX高速收发器,实现了基于JESD204B协议的数据发送和数据接收接口。在仿真测试平台,将构造的正弦信号送入发送接口,再经接收接口解析出来,与发送的原始数据比较,验证JESD204B数据传输接口的逻辑功能。经测试,发送前的原始数据与从接收接口解析出的数据一致,所设计的电路实现了基于JESD204B协议的数据传输功能。

关键词: JESD204B实现;高速串行传输;采集系统设计

Abstract: A data transmission interface based on JESD204B protocol is realized with Xilinx FPGA GTX transceivers to solve the problem of PCB routing complexity and inter symbol synchronization in AD acquisition project.The original data and the received data from the receiving interface are compared on the simulation platform to verify the logic function of JESD204B data transmission interface.Test results show that the original data are consistent with the received data.

Key words: implementation of JESD204B;high speed serial data transmission;design of data acquisition system
