• 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.
