The following table shows the signals of the Serial Interface of the Ethernet IP subsystem.
Table 40.  Serial Interface Signals
Signal Name Direction Description
p<n>_tx_serial[CHANNELS_PER_PORT] Out

TX serial data.

Each tx_serial bit becomes two physical pins that form a differential pair.

For 10G/25G/50GAUI-1/100GAUI-1: CHANNELS_PER_PORT=1

For 50G CAUI-2/100G CAUI-2/200GAUI-2:

CHANNELS_PER_PORT=2

For 40G CAUI-4/100G CAUI-4/200GAUI-4/400GAUI-4: CHANNELS_PER_PORT=4

For 400GAUI-8: CHANNELS_PER_PORT=8

p<n>_rx_serial[CHANNELS_PER_PORT] In

RX serial data.

Each rx_serial bit becomes two physical pins that form a differential pair.

For 10G/25G/50GAUI-1/100GAUI-1: CHANNELS_PER_PORT=1

For 50G CAUI-2/100G CAUI-2/200GAUI-2: CHANNELS_PER_PORT=2

For 40G CAUI-4/100G CAUI-4/200GAUI-4/400GAUI-4: CHANNELS_PER_PORT=4

For 400GAUI-8: CHANNELS_PER_PORT=8
