The input clock of Cyclone 3 can use a clockout from a ARM?

:( 

I want to use the input clock of Cyclone 3 from a ARM's output clock,does it can? It can reduce a oscillator. Does anybody use the source clock as this way?

Any clock signal that follows one of the Cyclone III's I/O standards can be used as a clock source, you don't absolutely need an oscillator.

What standard the clock source should meet?

There is a table of accepted I/O standards on page 6-12 of that document (http://www.altera.com/literature/hb/cyc3/cyc3_ciii51007.pdf). 

If you plan to use a pll with that clock signal, be sure to connect it to one of the dedicated clock inputs and that it's frequency is within the acceptable range of the pll.

Thank you very much.
