Note to Table 2–8:
(1) OCT calibration accuracy is valid at the time of calibration only.
Calibration accuracy for the calibrated on-chip series termination (RS OCT) and
on-chip parallel termination (RT OCT) are applicable at the moment of calibration.
When process, voltage, and temperature (PVT) conditions change after calibration,
the tolerance may change.
Table 2–9 lists the Arria V OCT without calibration resistance tolerance to PVT
changes.
