Latency

The following table shows the latency of the transmit and receive paths of the 800G Ethernet RS-FEC IP core.

The FEC IP measures latency from input to output and does not include the latency of the transceivers used for serial I/O. The latency through the DCMAC is included in these figures.

Table 1. Latency
Path Latency (Clock Cycles) Latency (ns @ 332.03125 MHz)
Transmit path 66 198.9
Receive path 80 240.9
