Table 5. Input Characteristics, V
NOTE 1: For the input crystal and REF_CLK frequency range, the M value must be set for the VCO to operate within the 250MHz to 500MHz
range. Using the minimum input frequency of 14MHz, valid values of M are 286 ≤ M ≤ 511. Using the maximum input frequency of 27MHz,
valid values of M are 149 ≤ M ≤ 296.
