testing.
1. Jitter on master clock input (XIN) is 100 ps pp or less.
2. Jitter on reference input (REF0-3) is 2 ns pp or less.
3. Normal Mode selected.
4. Holdover Mode selected.
5. Freerun Mode selected.
6. Jitter is measured without an output filter.
7. Accuracy of master clock input (XIN) is 0 ppm.
8. Accuracy of master clock input (XIN) is 100 ppm.
9. Capture range is programmed to +/-20 ppm; inaccuracy of XIN shifts this range.
