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.
5
Contact factory for availability.
