NATIVE-R9

The NATIVE-R9 is a 9U, 19”-wide high-end MTCA-Chassis, which is perfectly suited for high availability physics applications. Its complex infrastructure offers greatest possible flexibility and efficiency within a single system.

The system can be driven by up to four double Power Modules, which can be operated in different modes to ensure various levels of redundancy. With an optional LLRF-Backplane, two further Power Modules can be inserted from the rear side and work as RPM.

Up to two double MCHs are supported, with the option to connect an additional MCH-RTM to one of them. By default, the NATIVE-R9 features a dedicated JTAG-Slot, which – if populated with a NAT-JSM – enables permanent JTAG functionality without blocking a separate AMC-Slot.

From the front, up to 12 double mid-sized AMCs can be installed. Each of them can be expanded by 12 double mid-sized µRTMs inserted from the rear side of the chassis.

With the optional LLRF-Backplane, the NATIVE-R9 supports up to three additional eRTMs, as well as two Rear Power Modules (RPMs).

The NATIVE-R9 comes with an optional White Rabbit support, an Ethernet extension protocol.
