Serial Gigabit Media Independent Interface (SGMII)
Serial Gigabit Media Independent Interface (SGMII)
SGMII uses two data signals and two clock signals to convey frame data and link rate information between a 10/100/1000 PHY and an Ethernet MAC. The data signals operate at 1.25 Gbaud and the clocks operate at 625 MHz (a DDR interface). Due to the speed of operation, each of these signals is realized as a differential pair thus providing signal integrity while minimizing system noise.
