DLY_X Threshold Voltage and Charging Current
Mismatch
The two other error sources come from the IC itself and are
the differences in the DLY_X threshold voltage, (DLY_Vth)
when the GATE charging latch is set and the DLY_X
charging current, (DLY_ichg) across the four individual I/Os.
Both of these parameters are bounded by specification and
Figure 28 illustrates that with a common capacitor the typical
error contributed by these factors is insignificant as both
DLY_X traces overlay each other.
