Skew between the earliest and the latest
output transitions among all outputs.
Skew between the earliest and the latest
output transitions among all same class
outputs.
Skew between the nominal output rising
edge to the inverted output falling edge
Skew between non-inverted outputs
running at different frequencies
Skew between nominal to inverted outputs
running at different frequencies
Skew between nominal outputs at different
power supply levels
Skew between the outputs of any two
devices under identical settings and
conditions (VDDQ,VDD,temp,air flow,
frequency, etc)
Measured at VDD/2
Measured at 2.0V for VDD = 3.3V and at
1.7V for VDD = 2.5V.
Measured at 0.8V for VDD = 3.3V and at
0.7V for VDD = 2.5V.
Measured at 0.8V-2.0V for VDD = 3.3V
and 0.7V–1.7V for VDD = 2.5V
