SNIP The Cyclone 2’s had a minimum rated PLL > input of 20(?) MHz. The later parts bumped that down to 10 MHz. Much > more TimeNuts compatible. > > Bob > Bob Hmmm ... 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 perspective) http://tinyurl.com/opvng2y 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.
