Hi Jeff,
The PFB part of the circuit looks good, assuming C116, C117, C118 are 0.1uF. I am also attaching the schematics of DP83848I-POE-EK for reference.
What voltage are you measuring near those pins 18,37, 23?

Hello Adrian,
Thank you for reply.
I have an additional question.
I think DP83848 is confirmed compliance test with EVM by TI.
When they use EVM for compliance test, which EVM should they use?
DP83848I-POE-EK or DP83848K-MAU-EK?
Or each EVM are OK for…
