Design of High-speed Data and Long-distance Transmission System Based on FPGA

摘要

Design scheme of higb-speed and longdistance transmission system based on FPGA is proposed in this paper. The scheme implements serial/parallel conversion, parallel/serial conversion, LVDS' drive and receive through FPGA, it solves some problems such as the voltage level conversion of different interface standards, impedance matching, the signals' attenuation and resumption in the process of long-distance transmission. The scheme has advantages of simple design, strong anti-jamming ability, small size, low cost and high integration. Test result shows that the system works steadily and implemented serial data transmitting at the speed of 50 Mbps on 100 meters unshielded twisted pair with perfect transmission effect, which fully meets the design requirement.
