Application of Multi-channel Synchronization Based on JESD204B Protocol

超宽带数字波束形成已经成为阵列电子侦察系统的核心技术之一。大带宽数据的同步是制约波束形成技术的带宽与稳定性的关键。通过比较传统数据同步传输方案,提出了基于JESD204B协议的系统同步方案,分析了同步设计要点,并对同步信号的传输进行改进,同时采用该方案完成现场可编程门阵列(FPGA)片间同步的硬件测试,最后给出测试结果,为后期工程应用奠定基础。

Ultra wideband digital beam forming （DBF） has been one of the core technologies of array electronic reconnaissance system. The synchronization of large bandwidth data is the key to control the bandwidth and stability of DBF technology.By comparing the traditional data synchro nization transmission schemes,this paper puts forward a system synchronization scheme based on JESD204B protocol,analyzes the synchronization design points, and improves the transmission of synchronization signals,completes the hardware test of field programmable gate array （FPGA） in ter chip synchronization by means of this scheme,finally gives the test results,which lays the foun dation for later engineering application.
