Hello,
I'm trying to design a circuit with a T1 interface chip, magnetics and
RJ45s. I'm having trouble deciding on which magnetics to use. How do I
determine what the pri:sec ratios should be? Is this dependant on the
T1 interface chip? The datasheet for the interface chip says 1:1 for
RX, and 1:2 for TX, but I was wondering what would happen if I used a
1:2 for RX as well? The reason I ask is because I would like to use the
magnetics from Pulse Engineering that have integrated IC-side
protection, and for some reason, they only come in 1:2 ratios. I was
hoping to gain a better understanding of what determines these ratios.
I know how transformers work in general, but what is it that determines
whether I need a 1:2, 1:1.2 etc...
Thanks,
J
