EMERSON 5X00419G01以太网链路控制器
DUART接口MVME7100使用MC864xD DUART的串行端口0提供前端访问异步串行端口接口。来自串行端口0的TTL电平信号SIN、SOUT、RTS和CTS通过板载RS-232驱动器和接收器路由至迷你DB-9前面板连接器。4.10 PCI-E端口0 MC864xD处理器的一个8x PCI-E端口连接到五端口PEX8533 PCI-E交换机。PCI-E交换机的每个下游端口都连接到PCI/PCI-X桥。MVME7100实现了四个独立的PCI/PCI-X总线段。PCI-X总线1使用PEX8114桥接器连接到PMC站点1，并根据安装的PMC动态配置为使用板载逻辑以33/66MHz PCI或66/100MHz PCI-X模式运行。PCI-X总线2使用PEX8114桥接器连接至PMC站点2，并通过板载逻辑动态配置为基于安装的PMC以33/66Hz PCI或66/100 MHz PCI-X方式运行。PCI-X总线3使用PEX8114桥连接到Tsi148，并配置为133MHz PCI-X模式。
DUART Interface The MVME7100 provides a front access asynchronous serial port interface using Serial Port 0 from the MC864xD DUART. The TTL-level signals SIN, SOUT, RTS and CTS from Serial Port 0 are routed through on-board RS-232 drivers and receivers to the mini DB-9 front panel connector. 4.10 PCI-E Port 0 One 8x PCI-E port from the MC864xD processor is connected to a five port PEX8533 PCI-E switch. Each downstream port from the PCI-E switch is connected to a PCI/PCI-X bridge. The MVME7100 implements four separate PCI/PCI-X bus segments. PCI-X bus 1 connects to PMC site 1 using a PEX8114 bridge and is configured dynamically, with onboard logic, to operate in 33/66MHz PCI or 66/100MHz PCI-X mode depending on the PMC installed.PCI-X bus 2 connects to PMC site 2 using a PEX8114 bridge and is configured dynamically, with onboard logic, to operate in 33/66MHz PCI or 66/100MHz PCI-X mode depending on the PMC installed. PCI-X bus 3 connects to the Tsi148 using a PEX8114 bridge and is configured for 133MHz PCI-X mode.
