2.16.2. Time-of-Day Interface

A separate time-of-day (TOD) interface is available for each port within a reconfiguration group. Every time-of-day port in a reconfiguration group must be driven regardless of the number of active ports being used.

For Basic and Advanced timestamp accuracy modes, all time-of-day data must be synchronized to the same master time-of-day module.

The table describes the interface details for different numbers of ports.
Table 68.  Signals of the Time-of-Day (TOD) InterfaceFor signals description, refer to the F-Tile Ethernet Intel FPGA Hard IP User Guide.
