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 is measured with the optional phase noise filter capacitor in place.
Phase noise depends on the carrier frequency.
4. Subject to technical modification.
5. Contact factory for availability.
