NOTE: For the input crystal, CLK/nCLK and REF_CLK frequency range, the M value must be set for the VCO to operate with-
in the 600MHz to 750MHz range. Using the minimum input frequency of 12MHz, valid values of M are 50 ≤ M ≤ 62. Using the
maximum frequency of 40MHz, valid values of M are 15 ≤ M ≤ 18.
