Notes:
8. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
9. High frequency AC electricals are guaranteed by design and characterization.
10. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps.
11. Deterministic jitter is measured at 2.5Gbps/3.2Gbps with both K28.5 and 223–1 PRBS pattern.
12. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
n–Tn–1 where T is the time between rising edges of the output
signal.
13. Total jitter definition: with an ideal clock input of frequency ≤ fMAX, no more than one output edge in 10
12 output edges will deviate by more than the
specified peak-to-peak jitter value.
