Note 1.
Outputs loaded with 50-t- ground.
Note 2.
fMAX is defined as the maximum toggle frequency, measured with a 750mV LVPECL/HSTL input. HSTL output swing is > 400mV.
Note 3.
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.
Note 4.
The VPP (min.) is defined as the minimum input differential voltage which will cause no increase in the propagation delay.
Note 5.
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.
Note 6.
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. This parameters includes within bank skew and bank-to-bank skew.
Note 7.
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.
Note 8.
Cycle-to-cycle jitter definition: The variation in period between adjacent cycles over a random sample of adjacent cycle pairs. TJITTER_CC =Tn–Tn+1
where T is the time between rising edges of the output signal.
Note 9.
Total jitter definition: with an ideal clock input, no more than one output edge in 1012 output edges will deviate by more than the specified peak-
to-peak jitter value.
