Hi,
basically all you need to know is written in the datasheets ... and given/required by the application.
As long as the "output specifications" of the oscillator meets the "input specifications" of the two connected devices ... including the application conditions ... there is no problem in driving multiple devices from one source.
And yes, I´ve rather often used one clock source for several ICs.

You´re a quite experienced forum user and already did some electronics projects.
Thus I´m a bit surprised about the question and your given/missing informations.
* you miss to give rather important informations like: clock frequency and supply voltage..
* you use an "oscillator" .. so you clearly don´t connect a crystal, but still you refer to "crystal load capacitance"
* also you should know that the schematic is a good source of information what you are trying to do. Without it we need to guess a lot. (Pin names, wiring, termination ...)
* also you should already know that PCB layout has big influence in signal quality. Thus - even if the oscillator is able to drive both devices - it still depends on the PCB layout whether it will work on your board or not.
And "work" not only in the meaning that both IC´s operate correctly in your laboratory, but reliably work in the field with variable power supply, temperature... And also in the meaning: your application complies with the regulations (EMI, EMC, ....and so on)
One can say "we" need to "expect" that you correctly decided to use a 25MHz source and correctly decided to use the XI pins as clock input (There are other clock inputs, too). In the end we can not be sure about this. So if we have to guess this, do we also have to expect that you visited the manufacturer internet site for related douments? Like: did you read the "Hardware Design Checklist"?
I mean: you did not give much informations what you did so far.
