TIDA-01411: 10Gbps PoE PSE Injector

Part Number: TIDA-01411
Other Parts Discussed in Thread: TPD4E02B04, TPD1E01B04, ESD401, TPD4E1B06, BOOST-PSEMTHR-007

Dear *,

we are designing 10Gbps PoE PSE Injector, so we have a RJ45 data in connector and we want to protect this port.

Q1)

Would you recommend the same protection ( TCS-DL004-250-WH current protector + Bidirectional ESD diode CDSOD323-T05C) for 10Gbps as on TIDA-01411 between RJ45 data connector and PoE magnetics ? 

Or is it better to use TPD1E01B04 or TPD4E02B04 in combination with TCS-DL004-250-WH for 10Gbps?

or the 5.5V version ESD401 or TPD4E1B06?

I was going all of you PSE EVM kits like BOOST-PSEMTHR-007 and non has a protection between data port connector and magnetics, please see picture below.

What would you recommend to protect this port? Or this port doesn't need protection because from HOST side there are magnetics and on PSE injector data port there are also magnetics?

Q2) on BOOST-PSEMTHR-007 the MDCT pins are no connect why is that so? don't they need decoupling caps? ( Pin 12,6,1,7)

Best Regards,

David.

    David,

    BOOST-PSEMTHR-007 is not designed for surge protection. Regarding surge protection reference design, please refer to TIDA-01411. 

    For your question related to the protection components on TIDA-01411, we recommend using the same component as they are proved working through surge testing. You can use different components but you will need to verify it. Thanks.

    Best regards,

    Dear Penny,

    I referred to TIDA-01411, but his is not a PSE injector, we don't have the ETH phy on our device.

    In TIDA-01411 i understand how to protect the PoE output port. What would you suggest on how to protect the data input port in PSE injector?

    Please can you comment on Q2)  on BOOST-PSEMTHR-007 the MDCT pins are no connect why is that so? don't they need decoupling caps? ( Pin 12,6,1,7)

    Best Regards,

    David.

    David,

     

    We have expertise on the power side but unfortunately we don't have much experience on the data side. Our EVMs are designed to evaluate power module of the system. Please post your question to the PHY group and they should be able to support you. Thanks. 

    Best regards,

    Penny
