Reference Manual
Table 2–30 lists the SFP+ interfaces component reference and manufacturing
information.
CFP Interface
The CFP interface consists of 10 full-duplex transceiver channels. The CFP interface
can support both telecom and datacom applications such as Fibre Channel, Gigabit
Ethernet, ATM, and SONET/SDH.
Table 2–31 lists the pin assignments for the CFP interface and their corresponding
schematic signal names and Stratix V GX pin numbers.
13 SFP3_RDP 1.5-V PCML C4 Received data (output from the SFP+ interface)
9 SFP3_RS1 2.5-V LVCMOS AG33
Rate select. Controls the SFP+ interface transmitter.
When input signaling is high, the rate is > 4.25 GBps
and when input signaling is low, the rate
≤ 4.25 GBps.
19 SFP3_TDN 1.5-V PCML D5 Transmitted data (input to the SFP+ interface)
18 SFP3_TDP 1.5-V PCML D6 Transmitted data (input to the SFP+ interface)
3 SFP3_TXDISABLE 2.5-V LVCMOS AH10 Turns off and disables the transmitter laser output
2 SFP3_TXFAULT 2.5-V LVCMOS AU22 Interface transmitter fault
