基于 JESD204B 协议的雷达视频信号同步传输设计与实现

摘要

以宽带测向接收机中多波束比幅测向为背景，设计了基于JESD204B协议的高速背板视频信号同步传输方案。时钟、JESD204B协议参数的设计合理，实现了2块多通道视频幅度采集板与1块数据处理板之间线速率为6．25 Gbps的高速同步传输，解决了多波束比幅测向前多通道视频信号传输同步问题。%In the background of multi‐beam amplitude‐comparison direction finding in the broadband direction finding receiver ,this paper designs the synchronous transmission scheme for high‐speed backplane video signal based on JESD204B protocol .The design of clock and JESD204B protocol parameters is reasonable ,w hich realizes the 6 .25 Gbps high‐speed synchronous transmission be‐tween two multi‐channel video amplitude collection boards and one data processing board ,solves the synchronous transmission problem of multi‐channel video signals before multi‐beam amplitude‐comparison direction finding .
