Dears,

Ask a question about analog swith to impelment the signal switch between ethernet PHY and two transformer, please refer to the attached figure for more details.

Question:

I think it might need 4ch SPDT analog switch, and I found two part numbers: TS3A5018/TS3A27518E, but I am not sure it is the best solution?

the signal data rate is about 125Mbps between PHY and transformers.

Iven,

You have found 4-channel SPDT devices but we have some better solutions that are specifically designed to support differential Ethernet applications. Here are some device in the TS3LXXX and TS5LXXX families.

I would start by looking at the TS3L110 or TS5L100 which are 4 channel devices.

Here are some other posts that may also be helpful.

Thank you,

Adam
