2.4 AMC Interconnection
The AM4100 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 AM4100 Port Mapping is described below and illustrated in figure 2-5.
• Common Options Region:
•
Ports 0-1: two Gigabit Ethernet SerDes ports
• Fat Pipes Region:
•
Ports 4-7: one x4 PCI Express interface operating as a root-complex,
or alternatively
one x4 Serial RapidIO interface operating in host or agent mode
• Ports 8-9: two Gigabit Ethernet SerDes ports (optional)
• Extended Options Region:
•
Port 14: reserved for debug port
• Port 15: one serial port
