DP83867E: Output drive strength

Hello Onur Kusakoglu

Thank you for the query.

he driver strength i not configurable. The interface can connect to a MAC with 4 to 6 inches of trace length.

Can you please explain the use case and the need to know the drive strength.

The below thread could be of interest.

I have placed some series resistors and want to understand the power dissipation on these resistors. This is why I want to understand the drive strength of the PHYs. My traces are no longer than 2.5 inches. 

Hello Onur Kusakoglu

Thank you for the reply and information.

We support interface length between 4-6 inchs and so 2.5 inch should not be a concern.

We do have impedance control that you can use. Other than the link provided above  do not have a number that i can provide.

Okay thanks.
