Notes:
1. Measured from the V
DD
/2 of the input to V
DDOX
/2 of the output
2. Measured from the differential input crossing point to V
DDOX
/2 of the output
3. Defined as a skew within a bankwith equal load conditions
4. Defined as a skew between outputs at the same supply voltage, same frequency, and with equal load conditions. Measured at V
DDOX
/2
5. Defined as a skew between outputs on a different devices operation at the same supply voltages and with equal load conditions. Using the
same type of input on each device, the output is measured at V
DDOX
/2.
6. These parameters are guaranteed by characterizatoin. Not tested in prodution.
7. All parameters are measured at 250MHz with SEL [A:D] = 1 unless noted otherwise.
