Ethernet SGMII Interface

The Ethernet SGMII high-speed transceiver interface supports 10 Mbps, 100 Mbps, and 1 Gbps MAC Ethernet data rates for 1 Gbps SGMII as well as 2.5 Gbps SGMII data rates. All four Topaz transceiver banks and lanes support SGMII.

Figure 1. Transceiver Used as Ethernet SGMII
Each transceiver bank is called a "quad." Each quad has four lanes, and each lane supports an SGMII interface.
Tz200 and Tz325 Topaz FPGAs have four quads available.
Tz75 and Tz100 Topaz FPGA have two quads available.
Note: The number of transceivers is package dependent. Refer to the data sheet for the number of transceivers available in the package you are using.
