2.5. Fractured MAC SOP-Aligned Client Interface for FGT Transceivers

This section describes the fractured interface signals when you select the MAC SOP-Aligned client interface in the IP parameter editor.

The datapath interface consists of a fractured interface where the same set of signals is re-used for a single or multiple port datapath connections.

The following tables displays the ports details and the supported variants for each of the reconfiguration groups. The mode selection refers to the Ethernet mode parameter in the F-Tile Ethernet Multirate IP core Profile # IP Configuration tab.
