Table 117. RX XGMII Mapping to Standard SDR XGMII Interface
The 72-bit RX XGMII data bus format is different from the standard SDR XGMII interface. This table shows the
mapping of this non-standard format to the standard SDR XGMII interface.

When asserted, indicates successful link synchronization.
Disparity error signal indicating a 10-bit running disparity
error. Asserted for one
disparity error is detected. A running disparity error
indicates that more than the previous and perhaps the
current received group had an error.
Clause 37 Auto-negotiation status. The PCS function
asserts this signal when auto-negotiation completes.
