NAT-MCH Hub Module PCIe – Technical Reference Manual
5 Hub Module PCIe Basics
The
Hub Module
PCIe
is an expansion Module of the
NAT-MCH
. In addition to the
CLK
Module
it can be mounted on the
NAT-MCH Basic-Module
. The
Hub Module PCIe
is in a
6 Slot (
x24
) and in a 12 slot (
x48
) option available. With the
Hub Module PCIe
the 3
rd
tongue of the
NAT-MCH
connector to the MicroTCA backplane is always installed. With the
x48
option, additional the 4
th
tongue is installed. The
NAT-MCH Hub Module PCIe
implements the following major features:
•
support of PCI Express x4 switching function for fabrics D to G of up to 6 AMCs
(
Hub Module PCIe x24)
•
support of PCI Express x4 switching function for fabrics D to G of up to 12 AMCs
(
Hub Module PCIe x48)
•
support of spread spectrum clocking (distribution of the SSC signal is done by the
CLK Module
)
The
Hub Module PCIe
contains out of two PLX 8532 PCIe switches. The first PCIe switch
connects to AMC 1-6. This Switch is subsequent referred as 1
st
Switch or 1
st
PEX8532. The
second PCIe switch connects to AMC 7-12. This switch is subsequent referred as 2
nd
switch
or 2
nd
PEX8532.
