摘要
结合串行总线和令牌总线的特点,本文通过采用高性能芯片和合理的高速设计方法,提出了基于LVDS传输技术的令牌环网总线设计,详细阐述了该总线的设计原理及协议,并对整个环网设计进行了优化。并进行了硬件电路测试,结果表明:数据通过背板总线可实现高速传输且确保系统具有较高可靠性,满足了通用测试台中信号、数据高速传输的要求,具有很强的应用价值。
Unifying the serial bus and the token ring bus＇s characteristic, through the use of high performance chip and the reasonable high-speed design, the token ring network bus based on LVDS transmission technology is proposed in this paper. This article elaborated the design principle and the agreement of the bus, and the entire ring network design was optimized. The testing result of hardware circuit is that the data can be transmitted reliably in a high speed by this bus, the design has fulfilled the request of the test stand in the signal and the data high speed transmission, and it has a very huge application value.
