Description

The NAT-MCH offers power and system management for MTCA systems with up to 12 AMCs (13 in a non-redundant system without 2nd MCH), support for up to two Cooling Units and up to four Power Modules, which can be configured in various (redundant) configurations.

The single-width NAT-MCH aims for applications in MTCA.0 form factor, whereas the double-width NAT-MCH-M4 is the ideal choice for a MTCA.4 system. Functionality of both variants is the same in most parts, but moreover the NAT-MCH-M4 provides the option for a Zone3 connector and mounting space for two SATA-HDDs, both useable in combination with an optional NAT-MCH-RTM.

The NAT-MCH-M4 is the base of the NAT-MCH-PHYS/-PHYS80, which is designated for physics applications.

Generally, the NAT-MCH / NAT-MCH-M4 offers Gigabit Ethernet supporting port-based and tagged VLAN, Rapid Spanning Tree, as well as a port-based rate control via Fabric A. It also provides uplink ports on the front panel to interconnect to other systems.

For advanced clocking switching and distribution, a separate clock module can be mounted on the MCH base board:

  • The NAT-MCH-CLK mezzanine is a clock distribution module available in several variants. It features an onboard Stratum 3 type PLL, which can be locked on a clock signal coming from any AMC in the MTCA system. The front panel SMA connectors can be used to provide the internal clock to external devices or vice versa.
  • The NAT-MCH-CLK-PHYS mezzanine is a specialized clock module for physics applications, but is also ideally suited for uses cases, which demand a low-jitter and low-latency clock functionality.

If the base board is equipped with one of the HUB-Modules, SRIO, PCIe, or Ethernet are supported via Fabrics D-G towards the backplane and an optional front uplink.

  • The NAT-HUB-E HUB Modules are available in several variants. Depending on the chosen option, the module provides twelve ports of up to 40GbE to the backplane and three optical uplinks of up to 100GbE towards the front panel. Thus, this HUB-Module is highly suitable for applications demanding highest bandwidth Ethernet in MTCA towards the backplane and the front panel. XAUI support is available as an option, too.
  • The NAT-MCH-PCIEx48 HUB-Module provides an PCIe Gen3 x1/x4 link to each of the 12 AMCs in an MTCA system.
  • The NAT-MCH-PCIex80 HUB-Module features an PCIe Gen3 x1/x4 link to each of the 12 AMCs in an MTCA system, two x8 or one x16 towards the front panel (option), and one x16 link towards an optional RTM. Due to it double-width form factor, it is available for the NAT-MCH-M4
