DP83867IR: SGMII

Part Number: DP83867IR

Tool/software:

Hi All,

The DP83867IRRGZ works normally with SGMII.
I understand that the DP83867IRRGZ is for MII/GMII/RGMII, so why does it also work with SGMII?

Please tell me the difference between MII/GMII/RGMII and SGMII.

Best Regards,
Ishiwata

Hello,

We do not support DP83867IRRGZ for SGMII support. If customer intends to operate device in such a way, this is outside of the bounds of datasheet and responsibility of validating is solely place on customer.

Sincerely,

Gerome

Hi

Thank you for your reply.

I don't want to use SGMII with DP83867IRRGZ.

I mistakenly used DP83867IRRGZ instead of DP83867ISRGZ to set the MAC interface to SGMII, but it is communicating normally.
I would like to know why it is communicating normally.

Best Regards,
Ishiwata
