Gigabit Ethernet and Fibre Channel TBI Configuration
1000BASE-T Gigabit Ethernet and Fibre Channel TBI is implemented in much the same
way as Gigabit Ethernet (GMII). Table 10 shows the possible CP pin combinations you can
use and Figure 4 shows receive and transmit pin configurations by cluster. Table 12 shows
the signals and pinouts for a single cluster for Gigabit Ethernet and Fibre Channel TBI.
The unused pins for the two cluster configurations should be wired down using a resistor.
