2.15.4. TX 1-Step Timestamp Interface

A separate TX 1-step timestamp interface is available for each supported port within a reconfiguration group. The below table shows the interface details for different number of ports.

For 400GE rate, width of TX 1-step timestamp is 2x of other Ethernet rates. The interface signals of port 2 and port 0 are concatenated for 400GE port 0 usage as below:
{msb, lsb} == {i_p2_ptp_<signals>, i_p0_ptp_<signals>}
The table describes the interface details for different number of ports.
Table 69.  Signals of the 1-Step TX Timestamp InterfaceFor signals description, refer to the F-Tile Ethernet Intel FPGA Hard IP User Guide.
