Spartan 6 multi-clock Configuration

Hi, guys~

Is it possible to generate 3 clocks from CMT by using a single external clock source (32.768M Hz) on XC6SLX9 ?  

       1) 131.072M

       2) 100M

       4)  65M

Hi, Simon:

    I have worked it out~

    Accurate frequency is very important for my design, so i chained 2 PLLs & 4 DCMs together to generate these clocks i needed.

   Thanks for your reply~

Dear camelliasz,

 

you stated that the clocks must be very frequency accurate. What exactly are going to use these clocks for?

 

Best regards,

Martin
