摘要
Abstract
In order to ensure the reliability and accuracy of low voltage differential signaling (LVDS)used in remote test system serial data transmission,a (7,4)linear block code is proposed.At the expense of a certain effective bandwidth,the bit error rate of data transmission is greatly reduced,and the reliability of data transmission is improved by adding monitoring symbols. The driver CLC001 and the adaptive equalizer CLC012 are used as hardwares to compensate the attenuation of the signal in the long line transmission,improve the signal integrity and ensure the reliability of data transmission.Proved by simulation on a shielded twisted pair cable with a total length of 100 m,this system realizes zero bit error transmission of the serial data at the rate of 240 Mbit/s.关键词
