Table 44 Trigger-to-Signal Delay, Accuracy, and Uncertainty

Where, “1 master clock period” means one period of the

master clock used for the analog module.

“Accuracy” in the above table means a fixed delay that

could not be compensated by the analog module’s timing

calibration. Further, it has repeatability; if a test is done

under certain conditions of the analog module, the analog

module always starts “Trigger-to-Signal Delay

± the fixed

delay” after receiving the trigger signal when the “Uncer-

tainty” is zero.

“Uncertainty” means the dispersion of the start timing of

the analog module. It has no repeatability; the start timing

of the analog module may be different even if the test is

done under the same conditions. The analog module starts

in the uncertainty range around the “Trigger-to-Signal

Delay

± the fixed delay” point after receiving the trigger

signal. See the following figure.
