基于PCI总线无时钟LVDS数据采集卡的研究

Development of acquisition card for non-clock LVDS signal based on PCI bus

针对LVDS在航空测控领域的某特殊要求,研制开发了一种符合PCI总线规范的LVDS信号采集卡,该信号采集卡以FPGA为核心构建,具有本地存储大容量数据的能力,能够对高速大数据量的LVDS信号进行采集。同时在该信号采集卡的基础上这篇文章对无时钟LVDS信号的采集进行了深入研究,该数据采集卡可广泛应用于LVDS数据采集相关工程项目及研究生阶段的计算机接口技术的实验课程中。

according to the special needs of the LVDS in the fields of aeronautic measurement and control,we developed a data acquisition card for LVDS signal based on PCI bus.The acquisition card is developed based on FPGA,it is able to store large volume data and acquire the high-speed large-volume LVDS signal.At the same time,we have a deep study in acquiring non-clock LVDS signal based on this acquisition card.The acquisition card can be used widely in engineering projects related with LVDS signal and postgraduate courses of Computer Interface Technology.
