Connection to transformer

Question

Dear wiznet I am about to make a PCB with the w5500, and in the datasheet there is very limited information about the connection to the transformer. I have a setup like the one in the supplied picture, and my question is, what do i put between the w5500 and the transformer? Would it be fine with 4 50ohm resistors and 2 0.1µF capacitors and then nothing connecteed to the center taps ? Thanks in advance! 804×663 36.7 KB

Hi, kresten. I recommend to make same as our reference schematic. If you do not, it will not work well. Best regards.

So it is not possible to use a magjack with common center tap ?

Hi, kresten I recommend to make same as our reference schematic. Because we do not test other schematics. Best regards.

Hi kresten, I attached a reference schematic using a magjack with common center tap. Frankly speaking, this is not WIZnet’s official reference schematic yet. I know that they’re testing it internally. It will work well though WIZnet couldn’t guarantee it officially yet. Thank you. javakys
