OCT Calibration Accuracy Specifications

If you enable on-chip termination (OCT) calibration, calibration is automatically performed at power up for I/Os connected to the calibration block.

Table 16.  OCT Calibration Accuracy Specifications (for GPIO Bank)

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.

These specifications require RZQ reference accuracy of 240 Ω ±1%.

For specification status, see the Data Sheet Status table

Symbol Description Condition (V) Calibration Accuracy Unit
34-Ω and 40-Ω RS Internal series termination with calibration (34-Ω and 40-Ω setting) VCCIO_PIO = 1.2 ±20 %
50-Ω and 60-Ω RT Internal parallel termination with calibration (50-Ω and 60-Ω setting) SSTL-12 and HSTL-12 I/O standards –10 to +60 %
POD12 I/O standard ±15 %
