Jetson Xavier Synchronized by external clock

We are currently exploring two options: PTP: Basically use the PTP hardware support available in Xavier to increase the precision of the system clock synchronization as described in this post. Is there a way to feed the Xavier AGX with an external clock? Like a pin where we can connect a clock and then have Xavier using it as reference for the in…
