摘要
针对实时型相机对系统小型化、通用化及数据高速率可靠传输的需求,文中在研究高速串行器/解串器(SerDes)器件TLK2711工作原理的基础上,提出了高速串行全双工通信协议总体设计方案。文章以TLK2711为物理层、FPGA为链路层设计了高速串行全双工通信协议,对协议的实现进行了详细的描述。协议的在定制中力求做到了最简化,为上层用户提供简单的数据接口。试验中通过两块电路板的联调,完成了数据率为2.5Gbps的点对点高速传输,采用发送伪随机码测试,系统工作2小时,所测误码率小于10-12。
According to the technique specifications and characteristics of SerDes component TLK2711, the overall design of high-speed duplex communication serial data transmission is proposed for real-time camera system miniaturization, universal, and reliable high-speed transmission. Based on TLK2711 as physical layer and FPGA as data link layer, the protocol is described detail. The self-customization protocol is simple and provide for the simple upper user interface. The high-speed point to point transmission test of data rate up to 2.5Gbps is accomplished via two circuit boards. Using pseudo-random code for testing, system work for 2 hours, the measured BER is less than 10-12.
