Abstract
Design scheme of high-speed and long-distance transmission system is proposed, whose core is Cyclone II series FPGA chip EP2C5T144, based on low voltage differential signals (LVDS) interface technology. The scheme implements serial-to-parallel conversion, parallel-to-serial conversion, LVDS' driving and receiving through FPGA, it solves some problems such as the voltage 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. Experimental results show that the system works steadily, the serial data transmitting at the speed of 50 Mb/s on the 100 m unshielded twisted pair with the perfect transmission effect, which fully meet the need of design.关键词
