Notes:
5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
6. High-frequency AC-parameters are guaranteed by design and characterization.
7. Differential propagation delay is defined as the delay from the crossing point of the differential input signals to the crossing point of the
differential output signals.
8. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device operating at the
same voltage and temperature.
9. The part-to-part skew is defined as the absolute worst case difference between any two delay paths on any two devices operating at the same
voltage and temperature.
10. The VPP(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay.
11. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The
numbers in the table are referenced to VCCI. The VIL level must be such that the peak-to-peak voltage is less than 1.0V and greater than or
equal to VPP(min). The lower end of the CMR range varies 1:1 with VCCI. The VCMR(min) will be fixed at 3.3V – |VCMR(min)|.
12. OE set-up time is defined with respect to the rising edge of the clock. OE HIGH to LOW transition ensures outputs remain disabled during the
next clock cycle. OE LOW-to-HIGH transition enables normal operation of the next input clock.
13. Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles, Tn–Tn–1 where T is the time between rising edges of the
output signal.
