The MicroTCA from Schroff has been introduced to meet the requirements of the proposed MTCA.4 subspecification for high-energy physics and other advanced test and measurement applications. The physics community has adopted MicroTCA as an open standard for future data systems, in particle accelerators and similar research facilities. To ensure that MicroTCA satisfies the needs of users, PICMG (PCI Industrial Computer Manufacturers Group) has now developed a version of the specification known as MTCA.4 MicroTCA Enhancements for rear I/O and precision timing. The Schroff system consists of 5U high, 42HP wide chassis with backplane, power supply and fan. At the front, there are six AdvancedMC slots in double mid-size format, one MCH (MicroTCA carrier hub) slot and one slot for a plug-in 300W power supply, while the rear of the unit provides six RTM (rear transition module) slots in double mid-size format. The company says that with the system, there is a possibility to test the board mechanics and functionality of the rear I/Os, including integration of the defined MicroRTM modules into the existing shelf management. The optimised heat dissipation, forced ventilation of the front and rear slots provided by a built-in fan, can be controlled via the MCH.
