HI All
I need to validate Ethernet magnetics compatible to Jetson Nano SOM
In following JETSON NANO | PRODUCT DESIGN GUIDE on SOM found RTL8119I
I not see datasheet for this part
I want to use HX5181NL https://productfinder.pulseeng.com/productSearch/HX5181NL
It compatible to Jetson Nano SOM?

Thanks Pavel

I do not need PoE, and I have use this rj45-connector in my design,but it does not work.

My question :
about “common chroke” and “autotransformer”

for voltage-driver PHY , 2-wire common chroke can be placed to chip side or utp side.
for voltage-driver PHY, 3-wire common chroke only can be placed to chip side.

I have solved my bug, Nvidia design guide is about “B01” not “A02”, when I plug “B01” moudule in my carrier board, gigabit ethernet is ok (without any change)!.

so, if you have same trouble, please check that your moudle is “B01” or not.
