Notes:
1. Contact factory for improved stabilities or additional product options. Not all options and codes are available at all
frequencies.
2. Unless other stated all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency
control voltage, load, temperature (25°C).
3. Phase noise degrades with increasing output frequency.
4. Subject to technical modification.
5. Contact factory for availability.
