NOTES:
1) All voltages are referenced to ground.
2) This is the absolute accuracy of the master oscillator frequency at the default settings.
3) This is the percent frequency change that is observed in output frequency with changes in voltage
from nominal voltage at a temperature of TA = +25
°C.
4) This is the percentage frequency change from the +25°C frequency due to temperature at a nominal
voltage of 5V.
5) The maximum temperature change varies with the master frequency setting. The minimum occurs at
the default master frequency (fdefault). The maximums occur at the extremes of the master oscillator
frequency range (66MHz or 133MHz). (See Figure 5 below.)
6) The integral nonlinearity of the frequency adjust DAC is a measure of the deviation from a straight
line drawn between the two endpoints of a range.
7) DAC and OFFSET register settings must be configured to maintain the clock frequency within this
range. Correct operation of the device is not guaranteed if these limits are exceeded.
8) Frequency settles faster for small charges in value. During a change, the frequency changes smoothly
from the original value to the new value.
