Hi Sir

May we have RJ45 to RS485 converter reference circuit?

what we need to notice when we design it? DE/RE pin will control by outside CPLD.

Bogey,

I'm not sure I completely understand the application you're looking for. Do you mean you intend to transmit RS-485 signals over an RJ45 connector?

You can find our RS-485 & RS-422 reference designs here. I know that TIDEP0079 uses an RJ45 connector, but the THVD2410 does not have any reference designs specifically for that part at the moment.

Best,

Danny

Bogey,

Do you know what signal runs on the RJ45? It looks like the RS485 (THVD2410) needs to convert RS485 signal to Continuity_I and coverts Continuity_O back to RS485. If so, RJ45 connects to the A/B pins of THVD2410, while R=Continuity_I, D=Continuity_O.

Regards,

Hao
