I know this is a little left field but I am designing a board at the moment to use the USBizi and wiznet chip but really scratching my head over a small problem.
I understand that between the wiznet chip and the actual RJ45 jack there needs to be a set of magnetics.
So my question is this:
Where there heck are they?
a: Come built into the RJ45 Jacks and if so why do none of them say they have them built in?
b: Have to be added as a separate chip between the 2 items and if so why are there so few of them on the market? (Well that I can find anyway…)
Can please someone point out what the heck I am missing as this is driving me quietly mad… I know it is going to be simple and I just can’t see the solution.
Thanks in advance to all,
