NOTE 1: For the crystal frequency range the M value must be set to achieve the minimum or maximum VCO frequency
range of 250MHz to 700MHz. Using the minimum frequency of 10MHz, valid values of M are 200 ≤ M ≤ 511.
Using the maximum frequency of 25MHz, valid values of M are 80 ≤ M ≤ 224.
NOTE 2: Maximum frequency on FREF_EXT is dependent on the internal M counter limitations. See Application
Information Section for recommendations on optimizing the performance using the FREF_EXT input.
