摘　　要：设计并实现了一种用于MF-TDMA卫星通信系统的数据采集卡,采用PMC背板标准进行数据传输。该采集卡增加了数字下变频(DDC)模块,扩展了系统功能,使用EP2S60 FPGA芯片对PCI接口芯片PLX PCI9656进行逻辑控制,并基于PLX的SDK开发了采集卡的主机应用程序,实现了数据传输功能。实测证明,该采集卡具备良好的性能和很好的灵活性,既可以单独使用,也可作为数据处理母板的扩展系统。This article presents the design and implementation of a data acquisition board used in MF-TDMA satellite communication system,which transports data according to the PCI Mezzanine Card（PMC） specification. The function of the board has been expanded by adding a digital down converter （DDC） module. For designing the PCI interface,EP2S60 is used to control the logic timing of the PCI Bus Mastering I/O Accelerator PLX PCI9656. In addition, we have developed a host application program based on the SDK of PLX to control the board so that it can transport data accurately. The practice proves that the board has good performance and flexibility. It can be used as either an independent system or an extended part of the signal processing motberboard.
