    Hi Basit,

    PoE team is doing internal validation tests and the reply on E2E may be delayed for 3 - 5 business days. Sorry for the delay and thanks for your patience.

    Best regards,

    Diang

    Hi Basit,

    Please see the comments about TPS2378 circuit only: 

    1. Please add Bob-Smith termination circuits at both pair 12-36, and pair 45-78.  And the Bob-Smith termination ground should be isolated with other grounds. 

    2. The bulk cap of Class-4 normally needs > 22uF. 

    3. CDB is open drain pin. Please make sure U24 has EN internally pull up. 

    Best regards,

    Diang
