i'm using STRATIX iii and I read in the handbook that the VCCclkin need 2.5v POWER.. can I use 3.3v clock generator to stratix iii in my design?

    I believe the VCCclkin is for powering the differential clock input buffers (for say LVDS input clocks). You can certainly connect a 3.3V clock to the Stratix III. Obviously the recommendation would be that the VCCIO for that I/O bank be 3.3V.
