Ethernet

1/10/25/40/50/100 Gb/s

PCI Express Gen3: SERDES @ 8.0GT/s, 16 lanes (2.0 and 1.1 compatible)

Note: PCIe 3.0 x16 bus can supply a maximum bandwidth of 128Gb/s only (=16 * 8GT/s, including overhead), and therefore cannot support 200Gb/s when both network ports of MCX556A-ECAT run at 100Gb/s.
