Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at nomi-
nal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally.
This however may reduce the pull range.
