Additional Ordering Options
Additional ordering options available include custom temperature ranges, custom temperature stabilities, custom phase noise
requirements, low profile, custom supply voltage, hermetic option and improved g-sensitvity. These modifications require a
custom dash number - please contact the factory for additional information.
Notes:
1. Unless otherwise stated, all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency
control voltage, load, and temperature (25°C).
2. Retrace is defined as the frequency difference between the end of two 24 hour on power periods with a 24 hour off period in
between while at a constant temperature.
3. Phase noise degrades with increasing output frequency.
4. Not all options and codes available at all frequencies.
