    Newbie question: PLL on DE2 board (Cyclone 2) and VGA 1920x1200

    Thanks for the suggestion. My monitor did not like the different frequency but my TV tolerated it :)

    Newbie question: PLL on DE2 board (Cyclone 2) and VGA 1920x1200

    I realized that one solution is to have two PLL blocks (I tried one that goes from 50 to 40Mhz) and the other goes to my target frequency. Quartus is giving me some pains though ... it doesn't like that the input of the second PLL is coming directly from the first PLL. Hmm...

    Newbie question: PLL on DE2 board (Cyclone 2) and VGA 1920x1200

    Hi, I'm trying to generate a 193.16 Mhz clock using PLL for a particular VGA resolution (1920x1200@60Hz). I understand that this can be generated from a 50Mhz oscillator (that my board happens to have) using the following multiplier/divisor: 4829/1250. My version of Quartus (12.0 .. need old...
