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

The Cyclone V transceiver handbook shows the dedicated REFCLK input being fed onto the internal clock network implying (in my view) it can. However, it doesn't seem to be more specific as to whether that can then be used for clocking other registers or IO.

I suggest you let Quartus tell you. Put together a simple design or add a clocked output signal to your design driven from the transceiver's REFCLK. Then run it through Quartus. It'll give you a simple yes or no.

Cheers,
