10. Random jitter is measured with a K28.7 character pattern, measured at <f
11. Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles, T
12. Total jitter definition: with an ideal clock input of frequency <f
13. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each
