Orin NX Gigabit Ethernet MDI inter-pair skew

The Orin NX and Nano Design Guide v1.1 mentions on page 44 that the maximum pair to pair (inter-pair) skew requirement is 0.22mm (1.5 ps). It appears that this requirement was added to the latest revision of the Design Guide after the following question: About MDI inter skew spec for Jetson Onin

Is this new requirement really accurate? With previous Jetson models with integrated PHY (like TX2 and Xavier NX) there was no inter-pair skew requirement, and usually inter-pair skew requirements for the pairs between the PHY and magnetics are much less strict, such as 20mm.

Hi, that’s correct and updated as you found.
