Hello,
If the MAC the customer is using needs it then it needs to be connected. Also they should be okay with the default strap setting for this pin if left floating.
Kind Regards,
Joe

Joe,
Thank you. You mean it is required to use the default setting of MDIX ENABLE for pin34 if left floating, right?
Hello,
You are correct, The default setting of this pin will have to work for their design.
Kind Regards,
Joe
