The interfaces and features included in the development board:
 1-port PCIe x2 Interface
Supports the PCI Express 2.0 standard, and provides a standard PCIe x2
high-speed data transfer interface, for single-channel communication rates up to
5GBaud.
 2-port SFP Optical Interface
The 2-chanlle high-speed transceiver of ZYNQ's GTP transceiver, which is
connected to the transmission and reception of two optical modules, to realize
two high-speed optical fiber communication interfaces. Each fiber optic data
communication receives and transmits at speeds up to 6.25 Gb/s.
 Gigabit Ethernet Interface
2 channels 10/100M/1000M Ethernet RJ45 interface for Ethernet data
exchange with computers or other network devices. The network interface chip
uses Micrel's KSZ9031 industrial grade GPHY chip, one Ethernet connection to the
PS end of the ZYNQ chip, and one Ethernet connections to the PL end of the
7 / 60
