"Fout/Fref appears to be a rational number, PLL configured for Integer-N mode for best jitter performance (FS0)." highlighted below -
Does anyone know if there is a way to disable this default function & still program the part in FRACTIONAL mode and NOT INTEGER mode?

Hi Brooke,
The integer mode provides the best performance, so the clock wizard software is programmed to set the Integer mode PLL when PLL frequency differs lessthan 30-ppm between fractional and integer Mode.
There is no way to disable this fucntion. You may need to change the reference input to achieve a fractional PLL setting.
Thanks,
Pradipta.
