1. See Standard Frequencies and Ordering Information (Pg 8).
2. Parameters are tested with production test circuit (Pg 3).
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. The Vc Model is described below (Fig 1).
6. Parameters are described with waveform diagram below (Fig 2).
7. Not tested in production, guaranteed by design, verified at qualification.
8. For Frequencies >491.52 MHz, Jitter is Integrated across 50 kHz to 80 MHz.
For Frequencies <491.52 MHz, Jitter is Integrated across 12 kHz to 20 MHz. (Both per GR-253-CORE Issue3).
9. Tested with Vc = 0.3V to 3.0V.
