EMERSON 5X00105G14过程控制器
XMC扩展MVME7100通过使用78针堆叠连接器提供了额外的XMC/PMC模块功能。此连接器连接到处理器上的第二个PCI Express端口。通过使用两个扩展板，最多可以添加四个额外的XMC/PMC模块。有关更多详细信息和/或编程信息，请参阅XMCspan数据表。4.12电源MVME7100板载电压使用Linear Tech LTC3288双输出两相控制器和LTC3146单输出控制器生成。以下各节详细介绍了MVME7100的电源要求。电源排序为了满足MVME71000上各种组件的电源排序要求，电源控制器实施电压跟踪，从而允许电源输出在通电和断电期间同时跟踪彼此。+3.3V电源输出将用作跟踪参考。通电期间，所有电源输出在20毫秒内达到其最终值。
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.
