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 6.  Round-Trip Latency NumbersThe following numbers were obtained using the Quartus® Prime Pro Edition software version 24.1
Note: Latency is calculated based on recommended user clock frequency in design example
Protocol Transceiver Mode PMA Type Data Rate (Gbps) Number of Lanes Latency (ns)
