Hi, Team

Hope you are doing well!

My customer is using our DP83TG720R-Q1 and has one question:

My customer plans to do EMC testing and wants to know how to adjust the driving strength of our Ethernet device?

Thanks & Best Regards

Hi Jeff,

Please ask the customer to follow the software configurations in section 3 of this app note: https://www.ti.com/lit/an/snla371a/snla371a.pdf?ts=1701711672210

Which tests is the customer trying to pass? We don't recommend adjusting the drive strength of the our PHY, we usually expect it to pass without having to make drive strength adjustments.

Best regards,

Melissa
