Notes:
1 Contact factory for improved stabilities or additional product options. Not all options and codes are available at all
frequencies.
2 Unless otherwise 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.
