A Method Based on FPGA of Long Distance and High Speed Data Transmission

In current communication system, data transmission is high-speed and long-distance. The interface of low-voltage differential signaling (LVDS) becomes the first choice of data transmission. The most widely used is the LVDS differential chip. But this chip is often more expensive, the cost of development will be increased. Therefore, this paper presents a way to reduce cost. we use the software Quartus which produced by ALTERA company to call the macro module ALTLVDS to replace LVDS chip. In this way not only do we get the correct result, but also reduce the cost of the design.
