• Phase Noise and Jitter built to specification
including static and vibration.
• Low supply current
• QCI tests
• Tight frequency stability versus temperature,
supply voltage, and load variations
• Low spurious (see note 3)
• Low frequency aging, Allan Variance
• High-shock resistant
Notes:
1. The output level is determined by the supply
voltage, load, and package size.
2. Typical amplitude stability over temperature is
±10% or less.
3. Typical spurious level is better than -100dBc over
the spectrum of 100kHz to 1GHz.
