OCT Calibration Accuracy Specifications for Cyclone V Devices
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.
