I didn't know the CycloneII had a Min of 20Mhz.
Is that in some doc you can point me to ?
Well it seems to be 11Mhz for the CycloneII ... (Bummer from a T-Nut
I just tried to do a 10 => 100Mhz PLL in the EP2C5T144C8 , using the
"MegaWizzard" , and there were no errors or warnings.
Strange if the Min input is 11Mhz
Anyways , thanx for enlighten me Bob.
