• Frequency Select Input Supports Two
Pre-Defined Frequencies
• High Stability: ±25 ppm, ±50 ppm
• Wide Temperature Range
- Industrial: –40°C to 85°C
- Ext. Commercial: –20° to 70°C
• Excellent Shock and Vibration Immunity
- Qualified to MIL-STD-883
• High Reliability
- 20x Better MTF Than Quartz Oscillators
• Supply Range of 1.71V to 3.63V
• Short Sample Lead Time: 3.3V VDD.
Includes frequency variations due to initial tolerance, temp. and power supply voltage.
Input waveform must be monotonic with rise/fall time < 10 ms
Output Disable time takes up to one period of the output waveform + 200 ns.
For parts configured with OE, not Standby.
Output is enabled if pad is floated or not connected.
Time to reach 90% of target VDD. Power ramp rise must be monotonic.

Temperature Ranges
Junction Operating Temperature
Note 1:
—
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum +150°C rating. Sustained junction temperatures above +150°C can impact the device reliability.
