NOTE 1: For the crystal frequency range, the M value must be set to achieve the minimum or maximum VCO frequency range of 250MHz to
720MHz. Using the minimum input frequency of 10MHz, valid values of M are 200  M  511. Using the maximum input frequency of 25MHz,
valid values of M are 80  M  230.
NOTE 2: Maximum frequency on FREF_EXT is dependent on the internal M counter limitations. See Application Information Section for
recommendations on optimizing the performance using the FREF_EXT input.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device
is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal
equilibrium has been reached under these conditions.
See Parameter Measurement Information section.
NOTE: Characterized using 16MHz XTAL.
NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 2: See Applications section.
