Which side of magnetics do I place TS3L501E?

Hi Ryan,

Thanks for your response, I've uploaded a block diagram image.

Great, thanks for the response.

DO we risk damaging the mux if we drive the Ethernet lines while the mux is in power down mode or off?

I have seem other manufacturers of Ethernet muxes say that you must apply power to the device before driving Ethernet signals.

Thanks,

Adam

In other words, do the ethernet lines going to this part need to be tri-stated until we know the part has stable power?

Do you have a recommendation for a tri state buffer (or other solution) that would keep the network traffic isolated from the mux while the mux powers up?

Also, do you know how the multiplexer will be damaged if the ethernet pins are driven before mux powers up?

In terms of the ethernet pins being driven, does it matter if it's AC or DC?

We are AC coupled so if it's only DC that would damage the part then we should be OK, I think.
