1.5. Round-trip Latency

The following table includes the round-trip latency numbers for specific variants. The latency numbers were measured for the longest logical datapath for two highest lane rate and number of lanes variants, with FIFO level at 50 for the first packet.
Table 7.  Round-trip Latency NumbersThe following numbers were obtained using the Intel® Quartus® Prime Pro Edition software version 23.1
Note: Latency is calculated based on recommended user clock frequency in design example
