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 Figure 1.
