Hi Team

Customer is interested in our single-pair ethernet solution, especially power on 10base-T1L.

Just wondering if they can follow below reference design with only replacing with different PHY -> DP83TD510E?

Hi Andrew,

most likely it will not work properly with just replacing the PHY by a 10 BASE-T1L one. It is needed to modify the complete coupling network, as the frequency range used by 10 BASE-T1L is different than what is used with100 BASE-T1.

We have two applications notes focusing on PoDL for 10 BASE-T1L, there are also the parts mentioned which we have tested.
