Reference Manual
Table 2–30
lists the QSFP interfaces component reference and manufacturing
information.
SFP+ Interface
The development board consists of four SFP+ interfaces. All the SPF+ interfaces
connect directly to the Stratix V GX transceivers. The SFP+ interfaces can support
datacom applications such as 8.5 GBd Fibre Channel, 10 Gigabit Ethernet, or
10 Gigabit Fibre Channel.
Table 2–29
lists the pin assignments for the SFP+ interface and their corresponding
schematic signal names and Stratix V GX pin numbers.
