JAX vs JAXi vibration tests

Hello,

I’m looking at the datasheet for Xavier SoM (DS-09654-002_v1.5) and have some questions regarding the random/sine vibration tests. It seems like the JAX and JAXi are very similarly tested, if not exactly the same.

JAX

Test Test Conditions Reference Standards
Sine Vibration – 5G 2 sweeps 10-500 Hz, 5 Grms, 3 axes, 2 sweeps/axis, non-operational IEC60068-2-6
Random Vibration – 5G 10-500 Hz, 5 Grms, 8 hours/axis, non-operational IEC60068-2-64

JAXi

Test Test Conditions Reference Standards
Sine Vibration 10-500 Hz, 5 Grms, 3 axes, 2 sweeps/axis, FCT, Visual, operational IEC60068-2-6
Random Vibration 10-1000 Hz, 3 Grms, 3-axis, FCT, non-operational IEC60068-2-64
Random Vibration 10-500 Hz, 5 Grms, 3-axis, FCT, operational IEC60068-2-64

This is however not true when comparing the TX2 vs TX2i modules (taken from JETSON | TX2 SERIES | DATASHEET | 1.8):

TX2

Test Test Conditions Reference Standards
Sine Vibration – .75G 0.75G, 10-500 Hz, 1 sweep/axis, 3 axes total, non-operational IEC60068-2-6
Sine Vibration – .25G 0.25G, 10-500 Hz, 1 sweep/axis, 3 axes total, operational IEC60068-2-6
Random Vibration – 2G 10-500 Hz, 2 Grms,1 hour/axis, non-operational IEC60068-2-64
Random Vibration – 1G 10-500 Hz, 1 Grms,15 min/axis, operational IEC60068-2-64

TX2i

Test Test Conditions Reference Standards
Sine Vibration – 5G 10 sweeps 10-500 Hz, 5 Grms, 3 axes, 10 sweeps/axis, non-operational IEC60068-2-6
Sine Vibration – 5G 2 sweeps 10-500 Hz, 5 Grms, 3 axes, 2 sweeps/axis, operational IEC60068-2-6
Random Vibration – 5G 10-500 Hz, 5 Grms, 8 hours/axis, non-operational IEC60068-2-64
Random Vibration – 10G 10-500 Hz, 10 Grms, 1 hour Z-axis, operational NVIDIA Standard

Is the JAXi not supposed to be more rugged concerning vibration levels compared to JAX? Will the JAXi be tested using “Nvidia Standard” as the TX2i was?

Thanks in advance

Hi, please take the lists in datasheet as reference, that’s what it has been validated.

According to Nvidia’s JAXi announcement post the JAXi should have:
Expanded shock, vibration, and temperature

When reading the datasheet this doesn’t seem to be the case. Will the JAXi not be the subject to further tests in the future?

That is different on operational or non-operational. Anyway, the supported test cases are all in the datasheet as you can see.

Also you can refer the FAQ site below for the comparison.
