光纤传输数据结构和电路实现

Database of Fiber Transportation and Reality of Ciruit

光纤同步网是目前光纤通信的热点。同步数据体制（SDH）设备的开发成为目前国内几大通信公司的竞争焦点。本文讨论了SDH中数据传输的帧结构，针对该结构，设计了专用集成电路，经过MENTOR软件的模拟仿真，最后用XILINX4000EFPGA实现了该芯片。电路规模为40000万门，输入输出口最高速率大155MHz。

Fiber Synchronous network is a focus i fiber communication. The main communicationcompanies in our country are country are competing in Synchronous Digital Hierarchy. The frame structure of SDH is described here, then an applicatheialty integrted circult(ASIC) is designed.Ths MSIC is sdriulated on MENTOR's EDA tools, and realized using XILINX's 4000E FPGA. The chip has a scale of 40000 gates,and the maximum I/O frequency reaches 155MHz.
