6.2.1 Overview of Board Configuration Options
The parameters of the FCLKA option have the following properties:
• auto: The Module Management Controller configures the PCI Express reference
clock (FCLKA) via E-Keying
• in: AM4150 uses the PCI Express reference clock from the AMC Card-edge con-
nector (FCLKA)
• out: AM4150 uses the local PCI Express reference clock and generates the PCI Ex-
press reference clock to the AMC Card-edge connector (FCLKA)
• local: AM4150 uses the local PCI Express reference clock and the AMC clock
(FCLKA) is disabled

Note ...
[GbE] indicates that DTSEC4 used can be redirected to the front panel
connector J2 (GbE B) or optionally to AMC Port 10 for configurations which
provide GbE interfaces in the Fat Pipes Region, Port 8 or Port 9.
Note ...
There are two SATA ports available on the AM4150. The first SATA port is
routed to the AMC port 2. The second SATA port is routed either to AMC port 3
or to the SATA Flash module.
