Other Parts Discussed in Thread: THVD1450
Dear Specialists,
My customer is considering RS485 PHY with pulse trans former.
The customer uses ARCNET (2.5 Mbps, termination 100 Ω)
ARCNET uses half-duplex RS485 transceiver.
A common application example for ARCNET ids to insert a pulse transformer into the differential signal line of a half-duplex transceiver.
Could you please see below.

The customer is considering the ADM485 for a half-duplex transceiver.
I'm going to introduce THVD1451. Let me know if there are other better devices out there.
If possible, could you provide any information about reference designs, circuit examples, and design methods when using a half-duplex transceiver with a pulse transformer.
These information helps the customer consider TI's transceiver.
General information for non-isolated RS485 + pulse transformer is also preferred.
---Customer's Request
1. Could you please recommend a TI's RS485 transceiver suitable for the attached transformer is recommended.
ADM485 is also being considered as a competing candidate.
2. Could you please provide application examples such as recommended ICs, reference designs, and design guidelines?
examples of connection circuits between transceivers and pulse transformers (with or without external passive components),

I appreciate your great help in advance.
Best regards,
