1.3 FPGA C:
Select an FPGA part to be supplied in the C position. This fpga is connected to a memory
module socket. This FPGA is required to provide Multi-Gigabit serial communication. In order
to achieve 10 Gbps SelectIO operation, the –12 speed grade is required.
NONE
FX40 –10 –11 -11x –12 (This option makes the 200-pin SODIMM memory socket, one SMA
channel, four QSE cable channels, and one optical module socket unusable)
FX60 –10 – 11 -11x –12 (This option makes four channels of QSE cable unusable)
FX100 –10 –11 -11x –12
2 Multi-Gigabit Serial Options
2.1 Serial Clock Crystals
If you need to interface to a specific Multi-gigabit serial IO protocol, you may need to install a
custom crystal as a reference to the RocketIO clock synthesizer. Consult the Dini Group when
ordering for availability.
The following frequencies (in Mhz) are standard and Dini Group keeps a stock:
9.8304
12.890
14.318
16.000
21.477
24.576
25.000
The default option is 25.000 Mhz.
2.2 Module Sockets
XFP and SFP Modules provide 1.0 – 10.5 Gb optical serial communications to FPGA C.
DN8000K10PCI has two optical ports, each can be installed with either an SFP or XFP
connector. XFP modules operate only in the 9.5-10.5 Gb/s range. Available SFP modules
operate between 1-4.25 Gb/s. For 10Gb operation, a –12 speed grade FX part may be
required. These parts may not yet be available before.
If you have the FPGA C option, you may select one of the following options.
OPTICAL – SFP, SFP (default)
OPTICAL – XFP, XFP
