Note 1:
Crystal frequency can be divided by 2, 4, 8 and 16.
Note 2:
Direct output.
Note 3:
Depending on chosen output divider.
Note 4:
If the XPD pin is floating the output buffer is active. Oscillator is always running. At power down mode
the output is at high impedance.
Note 5:
Crystal load capacitance is dependent on a V
C
voltage. See figure 4 for C
L
for other V
C
voltages.
Note 6:
For calculating crystal pulling (S), see equation 1 on the page 5.
