Note 8.
All HSTL outputs loaded with 50
to GND.
Note 9.
The within-device skew is defined as the worst case difference between any two similar delay paths within a single device operating at the
same voltage and temperature.
Note 10. The part-to-part skew is defined as the absolute worst case difference between any two delay paths on any two devices operating at the same
voltage and temperature.
Note 11. Cycle-to-cycle jitter definition: The variation in period between adjacent cycles over a random sample of adjacent cycle pairs. TJITTER_CC =Tn–
Tn+1 where T is the time between rising edges of the output signal.
Note 12. Period Jitter definition: For a specified amount of time (i.e., 1ms), there are N periods of a signal, and Tn is defined as the average period of
that signal. Period jitter is defined as the variation in the period of the output signal for corresponding edges relative to Tn.
Note 13. Using recommended loop filter components.
Note 14. See “Timing Diagrams."
