6.2. Data Interface Signals

Table 12.  XGMII SignalsThe MAC drives the TX XGMII signals to the 10GbE PHY. The 10GbE PHY drives the RX XGMII signals to the MAC.
Signal Name Direction Clock Domain Description
xgmii_tx_dc[71:0] Input Synchronous to xgmii_tx_clk XGMII data and control for 8 lanes. Each lane consists of 8 bits of data and 1 bit of control. For interface mapping, refer to Table: TX XGMII Mapping to Standard SDR XGMII Interface.
xgmii_tx_clk Input Clock signal Clock for single data rate (SDR) XGMII TX interface to the MAC. It should connect to xgmii_rx_clk. This clock can be connected to the tx_pma_div_clkout; however, Intel recommends that you connect it to a PLL for use with the Triple Speed Ethernet IP function. The frequency is 125 MHz for 1G and 156.25 MHz for 10G. This clock is driven from the MAC.

The frequencies are the same whether or not you enable FEC.
