Focused on the low reliable problem of data existing in high-speed and long-distance transmission process, a method based on long transmission of LVDS and a new type of 8B/10B codec is proposed. The method selects and uses LVDS codec which is made in China, in the hardware circuit, the drive circuit and equalization circuit are adopted to compensate loss of signal in remote transmission; and in logic design, the new type of 8B/10B coding is realized to achieve DC balance of data in transmission and stability improvement in data transmission. Through the verification, error-free transmission of LVDS serial data can be realized at the rate of 500 Mb/s and on 240 m of balanced twisted-pair wire in the system.
