AM4024(E)

2.8 AMC Interconnection

The AM4024(E) 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 con-

nector 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.

2.8.1 Fabric Interface

The Fabric interface is the real communication path and comprises 20 high-speed ports providing

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 AM4024(E) port mapping is described below and illustrated in Figure 10.
