Filtering refclock signal on PFI


I would like to synchronize our PCI DAQ devices with a shared reference clock signal. I have a master device and its reference clock is exported to PFI1. The slave device's reference clock source is PFI0 (on slave device of course). I am afraid of that, there is some bouncing in the signal and the slave device cannot tune its oscillator with its PLL: Does it have any sense or a way to apply debounce filtering? In Timing property node, I did not find any related to the reference clock, just the source and rate.

As a B plan, the synchronization can be accepted by sharing the sample clock, but I would like you use the devices at different sampling rates. In this case, I found the filtering option, but which timebase should I select as source?

Thanks for the valuable answers.
