Have you considered the STMicro IMUs?

Yes, because it is the one the original paper uses.
But I'm not using them because ICM-42688-P has 32Khz Clock input options for all the IMUs to use a single and stable clock source.

ST can only do sampling synchronization, but not external clocking.

I will check. I'm pretty sure we did it with a single stable clock.
