摘　　要：若采用没有信号调节功能的LVDS芯片与设有驱动器预加重功能和接收器均衡功能的LVDS集成电路构成系统传输数据,电缆的长度便可最多到数百米。但这些系统想要进行数十公里长距离的数据传送,便应将LVDS信号经过光模块转成光信号来传输,并将之与LVDS系统一起搭配使用。采用DS92LV1023和DS92LV1224型号的LVDS芯片与驱动芯片CLC006和CLC014相互配合构成LVDS系统,再与光模块构成一个大系统便能够传输数十公里的距离。该系统已投入使用,其性能可靠、稳定、支持。If the LVDS chips without the function of adjusting signal coordinates with the integrated circuit with the pre-emphasis driver chips and the balanced LVDS functionality, the length of cable transmitting signal can be up to a maximum length of several hundred meters, lf these systems want to carry out dozens of kilometers long-distance data transmission, it should change LVDS signals through optical modules into optical signals for transmission, with LVDS system will be used together. The LVDS system employing the two LVDS chips called DS92LVI023 and DS92LV1224 which can coordinates with the driver chips CLC006 and CLCO14 integrates optical modules ,so it will be able to transfer several dozen kilometers away. This system is put into use, and its performance is reliable and stabile and stability and attainable.
