摘要
LVDS在高速数据传输中得到了广泛应用,但在传输过程中存在交流耦合,使得连续出现的0或1信号传输会出现丢数、误码等问题。通过介绍直流平衡在交流耦合中的作用,采用8b/10b编码的方法,实现了直流平衡。同时说明了8b/10b编码的具体实现过程中的重点和细节。通过仿真和实际数据收发,证实了该方案的可行性、准确性,提高了LVDS数据传输能力。
LVDS has been widely applied in high-speed data transmission. However, transmission has AC cou- pling. AC coupling makes the consecutive 1 or 0 signal transmission will be lost number and error. By introducing the function of DC-balanced in AC coupling, 8b/10b coding method is used to achieve DC-balanced and explained the 8b/10b encoded in the process of key points and detail. Through simulation and actual data transceiver, the feasibility and accuracy is confirmed. The LVDS transmission capacity is Enhanced.
