NAT-MCH BASE-Module– Technical Reference Manual
Version 2.10 © N.A.T. GmbH 8
1 Introduction
The NAT-MCH BASE-Module satisfies the basic requirements of the MicroTCA
Specification for a MicroTCA Carrier Hub. The main capabilities of the BASE-MODULE
are:
 management of up to 12 AMCs, two cooling units (CUs) and up to four power
modules (PMs)
 Gigabit Ethernet Hub Function for Fabric A ( up to 12 AMCs) and for the
Update Fabric A to a second (redundant)
NAT-MCH
The
NAT-MCH consists of a BASE-MODULE , which can be expanded with additional
extension PCBs. To meet also the optional requirements of the MicroTCA specification, a
CLK-MODULE and different HUB-MODULEs are available. With the CLK-MODULE the
following functions can be enabled:
 generation and distribution of synchronized clock signals for up to 12 AMCs
By extending the
NAT-MCH with a HUB-MODULE , hub functions for fabric D to G can be
enabled. With the different versions the customers have the opportunity to choose a
HUB-MODULE that fits best to their application. The versions differ in:
 max. number of supported AMCs ( up to 6 / up to 12)
 supported protocols:
 PCI Express
 Serial Rapid IO
 10Gigabit Ethernet (XAUI)
The features of the individual extension PCBs are described in more detail in the
corresponding Technical Reference Manuals.
