摘要
介绍了一种基于PCI总线的高速串口通信卡的设计,采用PLX公司的PCI9054作为PCI总线桥接芯片,FPGA作为本地总线的控制器和系统主控单元,选用LVPECL电平单模双纤光收发一体模块OCM3723为串口传输介质。最后介绍了利用vis-ual C+++DDK进行设备驱动开发。该设计的高速串口通信卡,其通信速率可达80 Mbit/s,传输距离超过10 km。具有设计简单、速率快、可靠性高、传输距离远等特点,已经成功运用于某航天遥测系统。
A kind of high-speed data transmission system based on PCI bus is presented,which exploits a PCI bridge chip PCI9054 which produced by PLX company,FPGA as local bus controller and system control unit, data transmission with the external system through duplex fiber single mode PECL transceiver 0CM3723. At last,the use of visual C ＋ ＋ ＆DDK for equipment driver development is introduced. Design of high-speed data transmission system,its communication rate of up to 80 Mbit/s, the transmission distance more than 10 km. It is simple in design, speed ,high reliability ,long distance transmission and other characteristics,is been successfully used in a space telemetry system.
