DP83TD510E: Capacitive coupling - Isolated alternative

franziskus

Part Number: DP83TD510E

Tool/software:

Hi,

is there an option to use a transformer instead of capacitive coupling for this device?

My customer is working in aviation industry and capacitive coupling is an issue during lightning events.

Thank you Evan! Do we have more collateral about this?

Is there a reference design that shows this implementation?

Best regards

Hi Franz,

There is an application note available for the power-over-data-lines design mentioned in that FAQ that may have some helpful details: https://www.ti.com/lit/an/snvaa25a/snvaa25a.pdf

For further questions I've CC'd the author on this thread.

Best,
