See the section. Accuracy 2 Measured on two outputs differentially as CLK and DB(0:9) are driven and XFR is held low. 3 Measured on two outputs differentially as the other four are transitioning by 5 V. Measured for both states of INV. 4 Measured from 50% of rising CLK edge to 50% of output change. Measurement is made for both states of INV. 5 Measured from 50% of rising CLK edge that follows a valid XFR to 50% of output change. Refer to for the definition.
