You can find all sorts of different transformer configurations. The magnetics
vendors have technical stuff that often knows what is good and in which
application, yet they also sell what they know isn't technically very good.
The
reason is that oftentimes customers require a specific configurat

The magnetics are made up of both a 1 to 1 isolation xformer and a cm choke. I
just stared at a schematic and I don't know if its an error, a single part or
generic, but for this one part the common mode choke was on the cable side for
the TX lines and on the IC side for the RX lines. I have never
Hello Muhammad,
Sorry for the little lengthy reply, but it is one of the most important
considerations when designing Ethernet front end - I tried to summarize it.
First you need to consider what kind of PHY driver you use. Some PHYs
transmitters are supplied from the center taps (CT), some ar

Hi Muhammad:
One thing to watch out for with integrated magnetics is that some of
