DP83867E: RGMII setup and hold time

Part Number: DP83867E

Hi team,

The reference point of setup time and hold time of RGMII is 50% of VDDIO?

There is a foot note which mention it's 50% clearly at the timing spec for SGMII but, there is no commnet for RGMII.

Please consider to add the claer comment at the next datasheet update.

Best Regards,

    Hi Atsushi,

    Yes you are correct, the reference point of setup time and hold time of RGMII is 50% of VDDIO. It is part of the standard we follow the standard for RGMII communication. Thank you for pointing out the comments for datasheet update.
