AMC Interconnection
The AM4011 communicates with the carrier board or the MicroTCA backplane via the AMC
Card-edge Connector, which is a serial interface optimized for high-speed interconnects. The
AMC Card-edge Connector supports a variety of fabric topologies divided into five functional
groups:
•
Fabric interface
•
Synchronization clock interface
•
System management interface
•
JTAG interface
•
Module power interface
The following sections provide detailed information on these interfaces.
2.4.1
Fabric Interface
The Fabric interface is the real communication path and comprises 20 high-speed ports pro-
viding point-to-point connectivity for module-to-carrier and module-to-module implementations.
The high-speed ports are separated in three logical regions as follows:
•
Common Options Region
•
Fat Pipes Region
•
Extended Options Region
The AM4011 port mapping is described below and illustrated in Figure 2-9.
•
Common Options Region
•
Ports 0-1:
two redundant Gigabit Ethernet SerDes ports
•
Ports 2-3:
two Serial ATA 150 ports
•
Fat Pipes Region
•
Ports 4-7:
one x4 PCI Express interface operating as a root-complex only
•
Extended Options Region
•
Port 14:
one Debug port
•
Port 15:
one Serial port
