Table 1–60
The XGMII TXC control signal is equivalent to the tx_ctrlenable signal; the XGMII
TXD control signal is equivalent to the tx_datain[7:0] signal.
Table 1–60. XGMII Character to PCS Code-Group Mapping
PCS-To-XGMII Code Conversion at the Receiver
In XAUI mode, the 8B/10B decoder in the Stratix IV GX and GT receiver datapath is
controlled by a XAUI receiver state machine that converts received PCS code groups
into specific 8-bit XGMII codes. This state machine complies with the IEEE P802.3ae
specifications.
Table 1–61
The XGMII RXC control signal is equivalent to the rx_ctrldetect signal; the XGMII
RXD control signal is equivalent to the rx_dataout[7:0] signal.
