XPS functional overview: Figures 5a, 5b show the functional diagram of the UT65CML8X8FD-EVB configuration.
Figure 5a shows all possible XPS switch connections by device programming using the SW GUI. Figure 5b shows
the XPS default switch connections at power-up.
In all cases, Port N RX Channel 0 connects only to Port N TX Channel 0, Port N RX Channel 1 only to Port N TX
Channel 1, Port N RX Channel 2 only to Port N TX Channel 2, and Port N RX Channel 3 only to Port N TX Channel 3.
This architecture is consistent with XPS use in SpaceVPX/VITA 78-based systems as an A/B Redundancy RapidIO /
XAUI port switch.
The piece-parts for only Channel 1 for all Ports 0-3 are installed with a) SMA Jacks, and b) AC-coupling capacitors.
Additional channels may be populated with these piece-parts depending on user system configuration and
requirements. Part numbers, manufacturers, and quantities are given in the Bill of Materials (BoM).
