1. See Standard Frequencies and Ordering Information tables (Pg 7) for more specific information
2. Parameters are tested with production test circuit below (Fig 1).
3. Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.
4. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
5. Measured from 20% to 80% of a full output swing (Fig 2).
6. Not tested in production, guaranteed by design, verified at qualification.
7. Integrated across stated bandwidth per GR-253-CORE Issue3.
8. Tested with Vc = 0.3V to 3.0V unless otherwise stated in part description
9. Broadband Period Jitter measured using Lecroy Wavemaster 8600A 6 GHz Oscilloscope, 250K samples taken
