NOTE:
1. Operation in the specified SYNC frequency range guarantees that the VCO will operate in its optimal range of 20MHz to F

x2. Operation with Sync inputs outside specified
frequency ranges may result in out-of-lock outputs. FREQ_SEL only affects VCO frequency and does not affect output frequencies.
