NOTE 1: For the input crystal and reference frequency range, the M value must be set for the VCO to operate within the
200MHz to 700MHz range. Using the minimum input frequency of 14MHz, valid values of M are 115 ≤ M ≤ 400.
Using the maximum frequency of 25MHz, valid values of M are 64 ≤ M ≤ 224.

Parameter Measurement Information section.
NOTE 1: Jitter performance using XTAL inputs.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the output differential cross points.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
