serial gigabit media independent interface (SGMII)

SGMII, Serial GigabitMedia Independent Interface; is a media-independent Ethernet interface for Gigabit Ethernet that supports data rates of 10 Mbit/s, 100 Mbit/s and 1000 Mbit/s.

The clock rate is 625 MHz, and transmission takes place using the DDR method, in which both edges of the clock pulse are used. Data is transmitted during the rising and also during the falling edge of the clock signal. The number of pins is 8. The SGMII interface has four data lines and 0/4 clock lines. To keep electromagnetic radiation as low as possible, differential data transmission, Low Voltage Differential Signal( LVDS) is used on dual wires.
