Part 3.10: SFP Interface
The AXU7EV FPGA carrier board has two optical interfaces. Users can
purchase SFP optical modules (1.25G, 2.5G, 10G optical modules on the
market) and insert them into these two optical interfaces for optical data
communication. The two fiber interfaces are connected to the two RX/TX of the
GTH transceivers of ZYNQ BANK225, and the data rate of each TX
transmission and RX reception is up to 12.5Gb/s. The reference clock of the
GTH transceiver is provided by the 125M differential clock of the core board.
The SFP Schematic detailed is shown in Figure 3-10-1:
