Note 5: F1 is the base frequency as defined by the package markings. F2 is a programmable frequency output. The output frequency of F2 is
derived from the base frequency, F1, by programming the F2 frequency select register and duty cycle (DC) bit in the TCXO control
register. The minimum output frequency is F1 / (2
8 + 1) with DC = 0 and f1 / [2 x (28 + 1)] with DC = 1.
Note 6: First year typical.
Note 7: 16.384MHz, 5V, +25°C with one of the two outputs enabled.
