基于FPGA的STM-64帧同步技术

摘要

A FPGA-based technology which realizes STM-64 frame synchronization in synchronous digital hierar-chy(SDH)communication was introduced. Composed of a 10,G optical module,a 10,G demultiplexing chip and a FPGA,the new technique is able to complete STM-64 frame synchronization in a FPGA which can only be realized with the help of a special chip. All data and frame format has been proved meeting the general international standards of SDH transmission and the technique was proved with wide application value in various SDH equipments.%介绍了一种采用 FPGA(现场可编程门阵列电路)实现 SDH(同步数字体系)通信中 STM-64信号帧同步的技术。该技术由1个10,G光模块、1个10,G解复用芯片以及1个FPGA组成，可以在FPGA中实现专用芯片才能实现的STM-64帧同步。该技术中所有数据及帧格式完全符合SDH传输国际通用标准，在各种SDH设备中拥有广泛的应用价值。
