Board Components & Interfaces

SFP A and B Interfaces (J6 and J7)

Two SFP standard cages (SFP_A and SFP_B) connect to the Stratix II GX

device’s transceivers and protrude through the PCIe panel. These two

interfaces are designed per the SFP MSA specifications. Modules that

comply with the SFP MSA specifications include networking standards,

such as asynchronous transfer mode (ATM), fiber distributed data

interface (FDDI), Fiber Channel, and GigE (both copper and optical).

The SFP MSA requires signals only up to 5.0 Gb/s, but standard modules

available today are typically 2.488 Gb/s synchronous optical net

(SONET) mode or below. The board is designed to deliver electrical

transceiver signals up to 5.0 Gb/s to each SFP connector. The two

channels of transceivers dedicated from the FPGA come from the same

transceiver block as two of the channels that are routed to the HSMC-A

transceiver interface. See “High-Speed Mezzanine Connectors A and B

Interface” on page 2–35.
