PLL clock input freq range

Hi All , I have a question about PLL clock input freq range In the Fitter report , we can see the suggested range of Input Freq What will happen if the actual input frequency is out of that...

Hi Justin ,

Thanks for your answer

I have a question further

If I have a frequency input range of 266MHz to 400MHz

And in the fitter report , it shows the Stratix II PLL could only receive input clock signal from 300MHz to 500MHz

what should I do to ensure the PLL could work properly @ 266MHz ?

Thanks
