Arria 10 CLKUSR - Can a spread spectrum clock be used?

I had checked there, but doesn't appear to give me any insight into the frequency accuracy of the 100MHz clock. If I use spread-spectrum and the center spread is 98-102MHz, will that violate timing or anything else related to CLKUSR functionality? It calls out that it needs a "stable" clock, but it doesn't say how stable it needs to be. That is what I'm looking for (freq accuracy + jitter specs).
