Part Number: DP83822H

Hi 

One of our machines features this family of PHY, can you confirm if it is Full duplex compliant as our end user is having difficulties with it and a Cisco switch.
Cisco report: the issue is with the Machine (Containing the relevant PHY) is  sending Half-Duplex markers when auto-negotiating 

Can you help?

    Hi Mike,

    Yes DP83822 can support full duplex links. Whether or not this is advertised will depend on the strap settings (or register configuration) of the PHY.

    Can you check that the PHY is strapped correctly? Here is the relevant table in the datasheet:

    Best,
