XMC擴(kuò)展MVME7100通過使用78針堆疊連接器提供了額外的XMC/PMC模塊功能。此連接器連接到處理器上的第二個(gè)PCI Express端口。通過使用兩個(gè)擴(kuò)展板，最多可以添加四個(gè)額外的XMC/PMC模塊。有關(guān)更多詳細(xì)信息和/或編程信息，請(qǐng)參閱XMCspan數(shù)據(jù)表。4.12電源MVME7100板載電壓使用Linear Tech LTC3288雙輸出兩相控制器和LTC3146單輸出控制器生成。以下各節(jié)詳細(xì)介紹了MVME7100的電源要求。電源排序?yàn)榱藵M足MVME71000上各種組件的電源排序要求，電源控制器實(shí)施電壓跟蹤，從而允許電源輸出在通電和斷電期間同時(shí)跟蹤彼此。+3.3V電源輸出將用作跟蹤參考。通電期間，所有電源輸出在20毫秒內(nèi)達(dá)到其最終值。
XMC Expansion The MVME7100 provides an additional XMC/PMC module capability through the use of a 78-pin stacking connector. This connector is connected to the second PCI Express port on the processor. Up to four additional XMC/PMC modules may be added by using two expansion boards. Refer to the XMCspan data sheet for additional details and/or programming information. 4.12 Power Supplies The MVME7100 on-board voltages are generated using Linear Tech LTC3828 dual output two-phase controllers and LTC3416 single output controllers. The following sections detail the MVME7100 power requirements.Power Sequencing To meet the power sequencing requirements of the various components on the MVME7100, the power supply controllers implement voltage tracking which allows the power supply outputs to track each other coincidentally during power up and power down. The +3.3V supply output will be used as the tracking reference. All supply outputs reach their final values within 20 milliseconds during power up.
