MOTOROLA GENERAL BUSINESS INFORMATION
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).
Table10
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.
