NOTE 1: For the crystal frequency range the M value must be set to achieve the minimum or maximum VCO frequency
range of 200MHz or 700MHz. Using the minimum frequency of 10MHz valid values of M are 320 ≤ M ≤ 511.
Using the maximum frequency of 25MHz valid values of M are 128 ≤ M ≤ 448.
NOTE 2: For crystal frequencies greater than 17MHz, a series tuning capacitor is required for proper operation.
For more information, please refer to the Application Information, "Crystal Input and Oscillator Interface".
