1Introduction
The NAT-MCH consists of a BASE-Module, which can be expanded with additional
PCBs. The 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 one or more
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
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
Through the extension of 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 applications. The versions differ in:
max. number of supported AMCs (up to 6 / up to 12)
supported protocols:
PCI Express
Serial Rapid IO
10Gigabit Ethernet
The features of the individual modules are described in more detail in the corresponding
Technical Reference Manuals.
A general arrangement of the different modules of a NAT-MCH is shown in the following
figure.

Hub Module
This Technical Reference Manual describes the NAT-MCH HUB-Module SRIO. In
addition to the CLK-Module it can be mounted on the NAT-MCH BASE-Module. The
HUB-Module SRIO is in a 6 Slot (“x24”) and in a 12 slot (“x48”) option available. With
the HUB-Module SRIO the 3rd tongue of the NAT-MCH connector to the MicroTCA
backplane is always installed. With the x48 option, additional the 4th tongue is installed.
The NAT-MCH HUB-Module SRIO implements the following major features:
support of SRIO x4 switching function for fabrics D to G of up to 6 AMCs (HUB-
Module SRIO x24)
support of SRIO x4 switching function for fabrics D to G of up to 12 AMCs (HUB-
Module SRIO x48)

NAT-MCH HUB-Module SRIO –Technical Reference Manual
Version 1.5 © N.A.T. GmbH 8
support of up to two SRIO x4 face plate uplinks and/or a SRIO x4 fabric update to
the second MCH (Uplink Option)
The HUB-Module SRIO contains out of two IDT CPS-1848 SRIO switches. The first SRIO
switch connects to AMC 1-6. This switch is subsequent referred as 1st switch or 1st CPS-
1848. The second SRIO switch connects to AMC 7-12. This switch is subsequent referred
as 2nd switch or 2nd CPS-1848.

2Overview
2.1 Major Features
Configurable x1 or x4 SRIO interfaces to 12 AMC modules
backplane update fabric to second MCH
operation baud rate per data lane 1.25 Gbit/s, 2.5 Gbit/s, 3.125 Gbit/s, 5Gbit/s or
6.25Gbit/s
