Notes:

7. High-frequency AC-parameters are guaranteed by design and characterization.

8. 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.

9. Random jitter is measured with a K28.7 pattern at: ≤6.4Gbps.

10. Deterministic jitter is measured with both K28.5 and 2

11. Contact factory for updated random jitter and deterministic jitter limits.
