Dear TI Team, 

As per datasheet of DP83867 PHY. Usually, 11K resistor is recommended on RBAIS(12) pin of DP83867 PHY chip. However SK-AM62P-LP  schematics have 10K resistor in parallel with 22pF. 

Can you please release the official document or update the value in DP83867 PHY datasheet.

    Hello Vaibhav Kundariya

    Thank you for the query.

    The Value changes help improve the Ethernet compliance test performance. 

    The changes have been made based on multiple iteration of Ethernet compliance testing.

    This is use case specific and can be made when the Ethernet compliance testing is a requirement.

    We do not have an official document on the changes to share.

    If there is any concern from your side on the value changes, i would recommend you revert back to the Ethernet PHY data sheet value recommendations.

    There may not be any significant difference for general Ethernet interface.
