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.

2.6.3.5.4. Serial Data Interface
Table 118. Serial Data Signals
Signal Name Direction Description
rx_serial_data
Input RX serial input data
tx_serial_data
Output TX serial output data
2.6.3.5.5. Control and Status Interfaces
Table 119. Control and Status Signals
Signal Name Direction Clock Domain Description
led_link
Output Synchronous to
tx_clkout
When asserted, indicates successful link synchronization.
led_disp_err
Output Synchronous to
rx_clkout
Disparity error signal indicating a 10-bit running disparity
error. Asserted for one rx_clkout_1g cycle when a
disparity error is detected. A running disparity error
indicates that more than the previous and perhaps the
current received group had an error.
led_an
Output Synchronous to
rx_clkout
Clause 37 Auto-negotiation status. The PCS function
asserts this signal when auto-negotiation completes.
