The Design and Realization of the Optical Electricity Transformation Module in SDH Synchronization Network

本文在分析SDH同步网技术和同步时钟控制方式的基础上,提出SDH同步网中光电转换模块的硬件系统的设计方案,从逻辑上进行了模块划分并确定了各个模块要实现的功能,详细介绍了关键芯片选取的型号和特征,重点分析了CPU和控制电路的具体实现方案,对其它相关模块的硬件实现也有论述。

This paper has analyzed the technology of SDH synchronization network and the synchronized clock control mode, proposed the design plan of the hardware system of the optical electricity transforma- tion module in the SDH synchronization network. Based on the logical division of the module to deter- mine the function that each module has to realize, this paper introduces the selected model of the key chip and the characteristic in details, and has analyzed concrete realization plan of CPU and the control circuit, and also elaborates the hardware realizations of other correlation modules
