Notes:
8. High frequency AC parameters are guaranteed by design and characterization.
9. Input-to-input skew is the difference in time from an input-to-output in comparison to any other input-to-output. In addition, the input-to-input skew
does not include the output skew.
10. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
respective inputs.
11. RJ is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps.
12. DJ is measured at 2.5Gbps/3.2Gbps, with both K28.5 and 2²³â€“1 PRBS pattern.
13. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T_n–T_n–1 where T is the time between rising edges of the output
signal.
14. Total jitter definition: with an ideal clock input of frequency ≤ f_MAX, no more than one output edge in 10¹² output edges will deviate by more than the
specified peak-to-peak jitter value.
15. Crosstalk is measured at the output while applying two similar frequencies that are asynchronous with respect to each other at the inputs.
