Notes:
6. Clock frequency is defined as the maximum toggle frequency, and guaranteed for functionality only. Measured with a 750mV signal, 50% duty cycle
7. Within-device skew is measured between two different outputs under identical transitions.
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
9. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps.
10. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2
11. Total jitter definition: with an ideal differential clock input of frequency
