EMERSON 5X00419G01以太網(wǎng)鏈路控制器
DUART接口MVME7100使用MC864xD DUART的串行端口0提供前端訪問異步串行端口接口。來自串行端口0的TTL電平信號SIN、SOUT、RTS和CTS通過板載RS-232驅(qū)動器和接收器路由至迷你DB-9前面板連接器。4.10 PCI-E端口0 MC864xD處理器的一個8x PCI-E端口連接到五端口PEX8533 PCI-E交換機(jī)。PCI-E交換機(jī)的每個下游端口都連接到PCI/PCI-X橋。MVME7100實(shí)現(xiàn)了四個獨(dú)立的PCI/PCI-X總線段。PCI-X總線1使用PEX8114橋接器連接到PMC站點(diǎn)1，并根據(jù)安裝的PMC動態(tài)配置為使用板載邏輯以33/66MHz PCI或66/100MHz PCI-X模式運(yùn)行。PCI-X總線2使用PEX8114橋接器連接至PMC站點(diǎn)2，并通過板載邏輯動態(tài)配置為基于安裝的PMC以33/66Hz PCI或66/100 MHz PCI-X方式運(yùn)行。PCI-X總線3使用PEX8114橋連接到Tsi148，并配置為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.
