1. Difference in phase error between two parts at the same voltage, temperature and frequency.
2. Output skew guaranteed for equal loading at each output.
3. Outputs loaded with 35 pF, measured at 1.5 V.
4. C
LOAD
= 35 pF.
5. All phase shift increments and variation are measured relative to 0FOUT0 at 1.5 V.
6. Clock period jitter with all FOUT outputs operating at 66MHz loaded with 25 pF using loop filter
shown. Parameter guaranteed, but not tested.
7. With 35 pF output loading (0.8 V to 2.0 V transition).
8. Depends on loop filter chosen. (Number given is for example filter.)
