Hi,
We have an eval board with a spartan FPGA and a 75MHz XTAL Within ourt design, we require an accurate 16MHz clock. It is not possible to generate this frequency using a single DCM, is it possible to chain 2 DCM's together to generate the 16MHz clock ?
(the obvious solution is to change the XTAL, but I'd like to know whether it is possible without changing the XTAL :-) )
Thanks for any feedback,
Steven
