Notes:

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

9. Random jitter is measured with a K28.7 character pattern, measured at 2.5Gbps.

10. DJ is measured at 2.5Gbps, with both K28.5 and 2

output signal.

than the specified peak-to-peak jitter value.

13. Crosstalk induced jitter is defined as the added jitter that results from signals applied to two adjacent channels. It is measured at the output

while applying two similar, differential clock frequencies that are asynchronous with respect to each other at the inputs.
