NOTES:
1. Skew measured between all outputs or output pairs under identical input and output interfaces, transitions and load conditions on any one device. For single ended and differential
LVTTL outputs, this measurement is made when each output voltage passes through V
DDQ
/2. For differential LVTTL outputs, the true outputs are compared only with other true
outputs and the complementary outputs are compared only with other complementary outputs. For differential HSTL outputs, the measurement takes place at the crossing point
of the true and complementary signals.
2. For operating with either 1.8V or 2.5V LVTTL output interfaces with both true and complementary outputs enabled. Inverting skew is the skew between true and complementary
outputs switching in opposite directions under identical input and output interfaces, transitions and load conditions on any one device.
3. Skew measured is the difference between propagation delay times t
PHL
and t
PLH
of any output or output pair under identical input and output interfaces, transitions and load conditions
on any one device. For single ended and differential LVTTL outputs, this measurement is made when each output voltage passes through V
DDQ
/2. The measurement applies
to both true and complementary signals. For differential HSTL outputs, the measurement takes place at the crossing point of the true and complementary signals.
4. Skew measured is the magnitude of the difference in propagation times between any outputs or output pairs of two devices, given identical transitions and load conditions at identical
