  • PCIe Gen3 x4 link to each of the 12 AMCs in an MTCA system
  • Two PCIe Gen3 x8 or one x16 link(s) towards front panel uplink
  • PCIe Gen3 x16 link to MCH-RTM

  • Clustering support for four virtual PCIe clusters with up to four PCIe Root Complexes

Description

The NAT-MCH-PCIex80 HUB-Module provides an 80-lane PCIe Gen3 switch that allows each of the 12 AMCs in a MicroTCA.4.x system to be connected by a x4 link. It provides either two x8 or one x16 optional optical PCIe uplink(s) towards the front panel. An optional NAT-MCH-RTM is connected by an x16 link.

The PCIe switch also accommodates higher bandwidths, i.e. x8 or x16, to a reduced number of AMC slots if the backplane provides appropriate connectivity.

Finally, the PCIe switch provides the ability to establish up to four virtual PCIe clusters and assign the AMC slots to these. The up to four PCIe Root Complexes can be any of the AMC-CPUs, the CPU located on the NAT-MCH-RTM, or an external PC.
