Hi,

I have a question about an unused interfaceon the SJA1105SEL.

AH1604 describes unused xMII interface.
Is there any recommended processing for unused SGMII interfaces?

SGMII pins do not require special termination if unused, may be left floating. In addition you can improve power dissipation by connecting both VDD_SGMII and VDDA_SGMII to GND.
