Hello:

Can someone help clarify the difference between SERDES, SGMII & 1000BASE-X?

Thanks,
Gavin
 

SERDES : Serializer DESerializer, used to convert from serial <==> parallel.
SGMII: Serial Gigabit Media Independent Interface, it is used to interface the MAC layer of the Ethernet to the PHY layer.
1000BASE-X : Optical fiber channel that meets GigaBit Ethernet protocol requirments.

so in a Ethernet system : MAC Layer <==> SGMII <==> SERDES <==> PHY (1000BASE-X)
