Hello Expert,

Our customer is considering to use this device for SGMII application.

As far as I confirmed, Following pin will be unused.

Then, could you please tell me how to treat those pins in SGMII appication?(e.g. short to GND, floating, etc...)

Best regards,

Hi Kurmaochi-san,

I would recommend sharing our schematic checklist with the customer. I think this will help answer their questions.

Most of these pins should be left floating. Note that RX_DV and RX_ER pins are used to set PHY address, so they may have strapping resistors.

Thanks,

Drew
