NOTES:
1. Outputs loaded with 50
to ground. Airflow
≥
300 LFPM.
2. 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.
3. Output swing greater than 450mV.
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.
6. The V
PP
(min.) is defined as the minimum input differential voltage which will cause no increase in the propagation delay.
7. V
is defined as the range within which the V
level may vary, with the device still meeting the propagation delay specification. The numbers in the
table are referenced to V
. The V
level must be such that the peak-
to-peak voltage is less than 1.0V and greater than or equal to V
(min.). The lower end of the CMR range varies 1:1 with V
CCI
. The V
CMR
(min) will be fixed at 3.3V
–
|V
CMR
(min)|.
8. 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.
