Notes:

10. Measured with 100mV input swing. See “Timing Diagrams ” section for definition of parameters. High frequency AC-parameters are guaranteed by

design and characterization.

11. 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.

12. Bank-to-bank skew is the difference in time from input to the output between banks.

13. 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. Total skew is calculated as the RMS (Root Mean Square) of the input skew and output skew.

14. Random jitter is measured with a K28.7 comma detect character pattern, measured at 1.25Gbps and 3.2Gbps.

16. Total jitter definition: with an ideal clock input of frequency

≤ f

specified peak-to-peak jitter value.

18. Crosstalk is measured at the output while applying two similar frequencies to adjacent inputs that are asynchronous with respect to each other at the

inputs.
