摘要
随着数字电路数据量的提高,数据的传输速率也越来越快,LVDS(低压差分信号)标准越来越多的应用在FPGA和ASIC器件中。文章对LVDS信号的特点进行了分析,说明了PCB设计中差分走线的注意事项并结合实际应用设计了一块LVDS接口板。
Along with the rapid development of digital circuit technology,higher data transmission rate is required.As a result,more and more LVDS(Low-Voltage Differential Signaling) standards are used in digital devices.The characteristic of LVDS is analyzed.The attentions on PCB design with LVDS are explained.And then a LVDS interface board is made.
