Request for understanding of ADIN1100 RX-TX mixing and termination resistor topology

Hello Yuanchen,

The part of the schematic is the external hybrid circuitry. 10BASE-T1L is a full-duplex technology, where both the Tx and Rx data go in the same two wires. This part of the circuit has the function of combining/separating the Tx and Rx data, allowing full-duplex comunication.

You can see more details about this section of the circuit in the MDI Interface section of the ADIN1100 Datasheet.

Raquel

Hello Raquel,

Thanks for your reply. We don't seem to manage to find the “MDI interface section” in the ADIN1100 datasheet (Rev A), as the link is https://www.analog.com/media/en/technical-documentation/data-sheets/adin1100.pdf.   Could you please point out the page number of the section for us, or the ink of the document if there is other document available? Would appreciate your help.

Regards,

Yuanchen

Hello Yuanchen,

Of course. The MDI Interface Section is on page 18 of the datasheet.

Regards,

Raquel.
