NOTES:
1) All voltages are referenced to ground.
2) This is the absolute accuracy of the output frequency at the default settings.
3) This is the percent frequency change that is observed in output frequency with changes in voltage
4) This is the percentage frequency change from the +25°C frequency due to temperature at a nominal
5) The maximum temperature change varies with the master frequency setting. The minimum occurs at
6) The integral nonlinearity of the frequency adjust DAC is a measure of the deviation from a straight
