5 CLK Module Basics
The
CLK Module
can be mounted on the
NAT-MCH Basic-PCB
. With the
CLK Module
,
the 2
nd
tongue of the
NAT-MCH
connector to the MicroTCA backplane is installed. The
NAT-MCH CLK Module
implements the following major features:
•
support of AMC clocks CLK1, CLK2 and CLK3 for up to 12 AMCs
•
support of CLK1 and CLK3 update for a second
NAT-MCH
in a redundant system
•
support of the front panel reference clock In/Output
•
Stratum 3 type PLL clock source for telecom applications with various output
frequencies
•
Telecom CLK signals can be distributed over all backplane clock connections and the
front panel interface
•
CLK1 and CLK2 from all 12 AMCs, the update clocks from a second
NAT-MCH
, or
a signal from the front panel interface can be used as reference for the PLL
•
a PCI Express compliant clock signal can be distributed via CLK3 to all 12 AMCs
(only possible with a installed PCI Express
Hub-Module
)
•
Support of M-LVDS
or
HCSL compliant driver and termination for CLK3
