What is SGMII SFP, Feature, Application, Related Products

The Serial Gigabit Media Independent Interface (SGMII) is a sequel of MII, a standard interface used to connect an Ethernet MAC-block to a PHY. It is used for Gigabit Ethernet(contrary to Ethernet 10/100 for MII). It differs from GMII by its low-power and low pin count serial interface (commonly referred to as a SerDes). To carry frame data and link rate information between a 10/100/1000 PHY and an Ethernet MAC, SGMII uses a differential pair for data signals and for clocking signals, with both being present in each direction (i.e., transmit and receive), giving 8 signal lines in total.
Applications

A typical chip-to-chip SGMII application may use between 12 to 48 full-duplex SGMII for 10/100/1000-Mbps Ethernet or Gigabit Ethernet links. For applications with SGMII links, the LVDS I/Os in Stratix V, Stratix IV, Stratix III, Cyclone V, Cyclone IV, Arria V, and Arria II GX FPGAs (fast speed grade) and HardCopy IV and HardCopy III ASICs (Altera devices with SGMII-capable LVDS I/Os) offer a preferred solution with low-power differential signaling capability, because these devices offer up to 132 LVDS transmitter and receiver pairs in the largest devices.
