AC ELECTRICAL CHARACTERISTICS
f
= 3.3V ±10%, T
100Ω termination between Q and /Q outputs. Airflow ≥300lfpm, or exposed pad soldered to ground plane.
f
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.
Set-up and hold time applies to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous applications,
set-up and hold time does not apply. 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.
The within-device skew is defined as the worst case difference between any two similar delay paths within a single device identical input transition,
operating at the same voltage and temperature.
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. Part-to-part skew is the total skew difference; pin-to-pin skew + part-to-part skew.
Cycle-to-cycle jitter definition: The variation period between adjacent cycles over a random sample of adjacent cycle pairs. T
where T is the time between rising edges of the output signal.
Total jitter definition: with an ideal clock input, no more than one output edge in 10
to-peak jitter value.
MAX
is defined as the maximum toggle frequency, measured with a 750mV LVPECL input or 350mV LVDS input. Outut swing is > 200mV.
