Notes:  
1. Contact factory for improved stabilities or additional product options including no pure tin options.  
2. Certain codes available for sampling and short lead time requests. Please review website for codes.  
3. 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).  
4. Contact factory for other frequencies. Phase noise degrades for frequencies greater than 10 MHz.  
5. Subject to technical modification.  
6. Contact factory for availability.
