1) Not subjected to production test, verified by design/characterization.
2) This value includes the maximum oscillator deviation.
3) This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
4) The sampling capacity of the conversion C-Network is pre-charged to
