Hi
I would appreciate it if you could reply as soon as possible.

About PCIe inter-pair(pair to pair) skew specification.

Jetson_Orin_NX_Series_and_Orin_Nano_Series_Design_Guide_DG-10931-001_v1.0 P50 [Length/Skew] specifies PCIe intra-pair skew as 0.15mm, but does not specify inter-pair(pair-to-pair) skew.

How long should the pair-to-pair skew be designed for?
There is concern that modules such as NVMe will not work if the skew between the pairs is incorrect.

Best regards.

Hi, PCIe pair to pair requirement was so loose, it would be nearly impossible to violate and still meet the max lengths.

Thank you for your reply.
I understand.
