Other Parts Discussed in Thread: PROFIBUS, ISO721, ISO1432, ISOW1432,
Hello,
I'm designing an isolated PROFIBUS interface, that shall be able to communicate at the maximum speed of 12 Mbps. I came across TI's Application Report SLLA177A (PROFIBUS Electrical-Layer Solutions https://www.ti.com/lit/an/slla177a/slla177a.pdf), where two single-channel ISO721 are used for TX/RX signal isolation. Also, design examples from other companies use two single-channel isolators.
Can I use a bidirectional isolator like ISO7721D for TX/RX signals coming from the transceiver? What are the pros/cons if using this solution?
Thanks in advance,
Alessio
