Can Cyclone V tranceiver REFCLK used as clock resource for general IO pins?

Hi, I am using Cyclone V. And right now there is 100MHz differential clock to connect to REFCLK in the transceiver part as clock source. Here I am just wondering whether this 100MHz REFCLK...

This is the sort of question Quartus will answer for you. Put a small, clocked design together. Constrain it so that the logic is clocked from the pin you're feeding the clock into and run it through Quartus. If it's possible Quartus will fit the design. If not, it won't.

Cheers,
