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.
Device | Number of Lanes | Lane Rate (Gbps) | Interlaken | Interlaken Look-aside | ||
---|---|---|---|---|---|---|
Number of Segments | Latency (Number of tx_usr_clk cycles) | Number of Segments | Latency (Number of tx_usr_clk cycles) | |||
E-tile (NRZ) | 12 | 25.78125 | 4 | 263 | 1 | 105 |
E-tile (PAM4) | 6 | 53.125 | 4 | 381 | 1 | 219 |
