1.This part supports the 1000 Base-T with SerDes interface by default. It can operate in 10/100/1000 Base-T with SGMII interface by reconfiguration of the PHY within the SFP.

2.This part uses the SFP’s Rx-Los pin for link indication and 1000 Base-T auto-negotiation should be disabling on the host system. It can operate in 10/100/1000 Base-T with SGMII interface by reconfiguration of the PHY within the SFP.
