6.1 VCXO Coarse Tune
The VCXO may be coarse tuned by a programmable adjustment of the crystal load capacitance via XCT[3:0]. The actual amount of frequency
warping caused by the tuning capacitance will depend on the crystal used. The VCXO tuning capacitance includes an external 6pF load
capacitance (12pF from the XIN pin to ground and 12pF from the XOUT pin to ground). The fine tuning capability of the VCXO can be enabled
by setting the XLVTEN bit to a logic-one, or disabled by setting the bit to a logic-zero.
