Part 3.2: SFP Interface
The AV7K325 FPGA development board has four optical interfaces. Users
can purchase SFP optical modules (1.25G, 2.5Goptical modules on the market)
and insert them into these four optical interfaces for optical data
communication. The four fiber interfaces are connected to the four RX/TXs of
the GNK transceiver of the FPGA BANK117. The TX signal and the RX signal
are connected to the FPGA and the optical module through a DC blocking
capacitor in a differential signal mode. Each TX transmit and RX receive data
rate is up to 10Gb/s. The reference clock of the GTX transceiver of BANK117 is
provided by the 125M differential clock of the core board.
