基于JESD204协议的AD采样数据高速串行传输

摘要

为解决传统采样数据并行传输时受码间同步及串扰影响的问题，研究了ADC采样数据的高速串行传输协议---JESD204协议，提出了一种具有自主知识产权的、基于FPGA中高速串行收发器GTX实现JESD204协议IP核的方法，实现了对ADC采样数据的高速串行传输并接收。实验表明，采用基于JESD204协议的高速串行传输方式可实现单通道3.2 Gb/s的传输速度，符合机载通信终端小型化的发展趋势。%To solve the ISI ( Inter-symbol Interference ) and lane synchronization problems in traditional parallel transmission method , the AD data serial transmission protocol---JESD204 is researched, and an implementation of JESD204 based on the high-speed transceivers GTX in FPGA is proposed. The experi-ment result shows, the serial transmission method based on JESD204 can achieve a transmission speed of 3. 2 Gb/s,and will satisfy the real project requirement.
