What is SGMII SFP Transceiver
SGMII SFP is high performance, cost effective modules. This article is to Learn about the SGMII SFP Transceiver. The SGMII (Serial Gigabit Media Independent Interface) is a supplement of MII, a standard interface used to connect an Ethernet MAC-block to a PHY. It is utilised 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.
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 …
