Vout between 0V and 280mV.
They are used to test device drive current capability to ensure Vih (MIN) plus a noise
margin and Vil (MAX) minus a noise margin are delivered to an SSTL_18 receiver. The
actual current values are derived by shifting the desired driver operating point (see out-
put IV curves) along a 21Ω load line to define a convenient driver current for measurement.
