=5V. They are given only as design guide-
lines and are not tested.
2)
These data are based on typical R
Smax
. The oscillator selection can be optimized in terms of supply current with high
quality resonator.
3)
R
Smax
is the equivalent serial resistance of the crystal or ceramic resonator.
4)
Data based on design simulation and/or technology characteristics, not tested in production.
5)
Data based on characterization results, not tested in production.
6)
In this condition, the capacitor to be considered is the global parasitic capacitor. In this case, the RC oscillator frequen-
cy tuning has to be done by trying out several resistor values.
