5.3.1 GMII Signal Multiplexing
The GMII balls are reassigned when using the RGMII mode or fiber mode. Table 16 “Line Side
Interface Multiplexed Balls” on page 58 specifies the multiplexing of GMII balls in these modes.
See Section 5.1.3, “Mixed-Mode Operation” on page 75 for proper configuration of the IXF1104
MAC in GMII mode.
5.3.2 GMII Interface Signal Definition
Table 26 “GMII Interface Signal Definitions” on page 95 provides the GMII interface signal
definitions. For information on 1000BASE-T GMII transmit and receive timing diagrams and
tables, please refer to Table 49 “GMII 1000BASE-T Transmit Signal Parameters” on page 142,
Figure 38 “1000BASE-T Transmit Interface Timing” on page 142, Figure 39 “1000BASE-T
Receive Interface Timing” on page 143, and Table 50 “GMII 1000BASE-T Receive Signal
Parameters” on page 143
