Notes:
1. Outputs loaded with 50
to V
CC – 2V. Airflow ≥ 300lfpm.
2. f
MAX is defined as the maximum toggle frequency measured. Measured with a 750mV input signal, all loading with 50 to VCC –2V.
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.
4. 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.
5. 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.
6. 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.
7. Random jitter is measured using K28.7 pattern, measured at
≤ f
MAX.
8. Cycle-to-cycle definition: the variation of periods between adjacent cycles, Tn–Tn-1 where T is the time between rising edges of the output signal.
9. Total jitter definition: with an ideal clock input of frequency
≤ f
MAX, no more than one output edge in 10
20 output edges will d eviate by more than the
specified peak-to-peak jitter value.
