Operating Temperature Range |
per Operating Temperature Ranges vs. Frequency Stabilities table below |
|
The maximum and minimum temperatures that
the oscillator device can be exposed to during oscillation. Over this
temperature range, all of the specified device operating
parameters are guaranteed.
|
|
Supply Voltage (VDD) |
2.5VDC ±5% |
|
The DC input voltage necessary for oscillator operation, specified in
volts.
|
|
Input Current |
2.0mA Maximum over Nominal Frequency of 12.800MHz to 25.999999MHz
2.5mA Maximum over Nominal Frequency of 26.000MHz to 40.000MHz
|
|
The amount of current consumption by an oscillator from the power
supply, typically specified in milliamps (mA).
|
|
| Output Voltage (Vp-p) |
0.8Vp-p Clipped Sinewave Minimum, External DC-Cut Capacitor
Required, 150pF NPO Recommended |
|
Load Drive Capability |
10kOhms // 10pF |
|
The maximum load the oscillator can drive specified in terms of the
number of gates or the type of load circuit (Figures 2, 3 and 4 in oscillator glossary of terms).
