The calibration accuracy for calibrated series and parallel OCTs are applicable at the
moment of calibration. When process, voltage, and temperature (PVT) conditions
change after calibration, the tolerance may change.
Table 1–13 lists the Arria II GZ OCT without calibration resistance tolerance to PVT
changes.
OCT calibration is automatically performed at power up for OCT-enabled I/Os.
When voltage and temperature conditions change after calibration, the resistance may
change. Use Equation 1–1 and Table 1–14 to determine the OCT variation when
voltage and temperature vary after power-up calibration for Arria II GX and GZ
devices.
