Notes:

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 PHYwithin 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.

3.This part supports the 10/100/1000 Base-T with SGMII interface by default.

Serial Interface Configuration (PHY Two-Wire Address 0xAC)

Register	Bits	Field	Mode	Description
27	3:0	HWCFG_	R/W	Changes to these bits are disruptive to the normal
		MODE		operation; hence, any changes to these registers must be
				followed by software reset to take effect.
				Upon hardware reset Register 27.3:0 defaults to the value
				in HWCFG_MODE[3:0].
				0100 = SGMII without Clock with SGMII Auto-Neg to
				copper
				1000 = 1000BASE-X without Clock with 1000BASE-X
				Auto-Neg to copper (GBIC)
				1100 = 1000BASE-X without Clock without 1000BASEX
				Auto-Neg to copper
