1. See Standard Frequencies and Ordering Information.

2. Parameters are tested with production test circuit below (Fig 2).

3. Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.

4. Measured from 20% to 80% of a full output swing (Fig 3).

5. Not tested in production, guaranteed by design, verified at qualification.

6. The FX-424 phase noise and jitter performance can be optimized for specific applications. Please consult with Vectron’s Application

Engineers for more information.
