DP83TC811R-Q1: -

Hi Matthias,

By inductive coupling are you referring to the CMC? The datasheet provides a list of recommended CMC part numbers. You may find the size of the coil in the respective datasheets.

Thank you,

Hello Nikhil,

I'm asking about the DC coupling that is implemented by using the capacitors C3 and C4. I want to replace it by a transformer coupling.

Kind regards,

Matthias

Hi Matthias,

Unfortunately the picture did not attach correctly, can you try re-uploading?

Are you referring to C3 and C4, the DC coupling on the MDI Low-Pass filter in Figure 136 in the datasheet? As Figure 135 in the datasheet shows, the Low Pass filter is optional, this can be removed from the circuit such that only the CMC, DC blocking caps, and common mode termination remain.

Does this answer your question?

Thank you,

Nikhil

Hello Nikhil,

my question is about the so called DC Blocking in Figure135.TypicalApplication(RGMII)

I want to replace the capacitive coupling with a magnetic one. This topic was already themed in this thread (Thread Link: ) But I wasn't satisfied with the answer and like to have more information about the size of the coils that are used for such a setup.

Kind regards,

Matthias

Hi Matthias,

We are looking into this issue and will provide feedback by Wednesday.

Thank you,

Nikhil
