I’m designing a carrier board for the Xavier NX, which includes Ethernet. However, the Ethernet is not an RJ-45 jack; the carrier board connects the Ethernet directly to other harnessing that eventually makes its way to a switch. Therefore, I need to include magnetics but no jack.
In the past I’ve found that various Gigabit Ethernet PHYs that I’ve used call out specific supported magnetics. Is that the case for the Realtek RTL8211FDI Gigabit Ethernet Controller than the NX uses? Unfortunately Realtek only provides information to development partners. I’m hoping that Nvidia or anybody else who is a development partner may be able to provide information about the required magnetics?
Interestingly there is nothing in the NX Design Guide about the Ethernet interface. Thanks!
