Description

The NAT-MCH-RTM is a COMExpress Type-6 carrier extension for the double-width NAT-MCH-PHYS80. As the term RTM indicates, the Rear Transisition Module is inserted from the rear side into a MicroTCA.4.1 chassis. Thus, the use of an RTM increases the number of interfaces, adds storage capacity or processing power etc. without populating a further slot from the front side. In combination with a COMExpress module, it replaces a processor Advanced Mezzanine Card (PrAMC).

The NAT-MCH-RTM is available in several variants, all of them are COMExpress carriers suitable for one of the following Type-6 modules supported by N.A.T. (others on request):

  • NAT-MCH-COMex-Ce-16: Celeron G-4932E dual core CPU with CM246 chipset and 2x 8GB DDR4 ECC
  • NAT-MCH-COMex-i3-16: Core i3® 9100HL quad core CPU with CM246 chipset and 2x 16GB DDR4 ECC
  • NAT-MCH-COMex-XE-32: Xeon® E3 E-2276ML six core CPU with CM246 chipset and 2x 16GB DDR4 ECC

Via the Zone3-Connector, the COMExpress-Module has access to a x16 PCIe Gen3 path, a GbE connection, and two SATA connections to the SSD(s) of the NAT-MCH-PHYS80. This makes the NAT-MCH-RTM with ComExpress-Module a fully featured replacement for a Processor AMC – including PCIe Root Complex functionality – without populating an AMC slot.

When used together with its RTM, the NAT-MCH-PHYS80 also connects the COMExpress-Module CPU with a x16 link to the PCIe Gen3 switch. As the fully user-accessible Intel CPU on the NAT-MCH-RTM can act as a PCIe root complex, this x16 PCIe link overcomes the bottle neck between the root complex and many PCIe based I/O payload AMCs, which in most MTCA.4 systems are connected by a x4 link only.

Together with an SSD storage, the combination of NAT-MCH-PHYS80 and NAT-MCH-RTM with a COMExpress-Module turns into a true single-slot fully user-accessible root complex at PCIe Gen3 speed.

Option -BM:

With the Backplane Manager (-BM) option, the NAT-MCH-RTM-BM allows the use of an optional LLRF-Backplane according to MTCA.4.1. The LLRF (Low-Level Radio Frequency) is located behind the standard AMC-Backplane. One of its purposes is distribution of high precision RF- and CLK signals among eRTMs and standard RTMs. Moreover, it allows managing eRTMs as well as µRTMs.

Together with the NAT-MCH-RTM-BM, the NAT-MCH-PHYS80 can handle up to two additional Power Modules.

Option -BM-FPGA:

Basically, the NAT-MCH-RTM-BM-FPGA provides the same functionality as the -BM option. Due to the additional FPGA, it offers a wide spectrum for user specific applications.
