Part 3.2: SFP Interface
The AV7K300 FPGA development board has four optical interfaces. Users
can purchase SFP optical modules (1.25G, 2.5G, 10G optical 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. 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.
