摘要
CYPRESS公司的HOTLINK产品作为物理层数据收发器目前在高速串行系统当中得到越来越广泛的应用。针对信号需要进行远距离传输的应用场合,文中分析了长铜缆作为传输介质时对系统信号传输性能的影响,指出了在长线传输设计中应着重注意的问题和相应的解决办法。并以CY7C954DX芯片为例,给出了一种适合HOTLINK产品的长线传输电路的设计。
The HOTLINK series product of CYPRESS is now widely used in the high-speed serial transmission system.Considering the circumstance of signal＇s transmission through long distance, this paper analysed the effect of long copper cables on signal propagation features. In addition,the related problems and the solutions that must be paid attention to in design are mentioned.then, a reference circuit that applies to HOTLINK product is produced.
