| 摘 要： | 采用无信号调节功能的低电压差分信号LVDS（Low-Voltage Differentical Signaling）器件接入通信设备，其电缆长度一般为几米；但采用具有驱动器预加重功能和接收器均衡功能的LVDS器件，其电缆长度可达数百米。采用LVDS接口器件的系统如果需长距离传输数据，可采用电缆驱动器^1]。该系统采用DS92LV1023和DS92LV1224型的LVDS器件与驱动器件CLC006和CLC014相配合，可实现传输300米的距离。该系统设计已投入使用，其性能可靠工作稳定。

| Abstract: | The length of twisted pair cable of access communications device is a few meters,which uses LVDS(Low-voltage differential signaling)without adjusting signal function.But the length of twisted pair cable of the device is up to 100 meters,which uses LVDS with driver pre-emphasis and the receiver balanced function.If the system adopting LVDS interface chip transmits the data for long distance,it should adopt the special chip in conjunction with LVDS chips for driving the longer cables.This system employs the t... |
