Jitter performance using XTAL inputs.
Defined as skew between outputs with the same supply voltage and with equal load conditions. Measured at the output
differential cross points.
This parameter is defined in accordance with JEDEC standard 65

Notes
1.
For the input crystal and TEST_CLK frequency range, the M value must be set for the VCO to operate with in the 200MHz to 700MHz
range. Using minimum input frequency of 12MHz, valid values of M are 17 ≤ M ≤ 58. Using the maximun frequency of 25MHz, valid
values of M are 8 ≤ M ≤ 28.
