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 (25C) 3 Phase noise degrades with increasing output frequency. 4 Subject to technical modification. 5 Contact factory for availability.
