These values assume 25MHz or 14.31818MHz inputs respectively. Using a higher or lower frequency

will scale these frequencies accordingly. The output frequecy selected by the FS inputs will also scale.

For example, 27MHz input with an FS selection of 100MHz will yield an output frequency of 27/25 x 100 =

108MHz.

Input frequency should be measured at the REF pin and tuned to 0 PPM to meet

ppm frequency accuracy on PLL outputs.
