Tool/software:

Hello,

Can you offer any device (like analog mux or FET switch for example) which can mux/switch 1 to 2 PHYs analog interface TD+/- and Rx+/- differential lines (differential lines between PHY and transformer).

Speed is 10/100M.

The idea is to switch one PHY analog output to two different RJ45s

Regards

Hello,

We do not offer such a device with 2 MDI ports with a single MII. The closest could be DP83849, which is a dual port device, but this too has to have 2x MII with no ability to mux. There would also be signal integrity concerns when placing a mux on the MDI lines.

Sincerely,
Gerome

Actually looks like TS3DV20812 can mux GIG lines.

However TS3DV20812 is for 4 pairs I need 10/100m which is two pairs.

Hi Edi,

If you would like, I can transfer you to the E2E forum for that part. This forum is specifically for PHYs.

Sincerely,
