OCT Variation after Power-Up Calibration
The definitions for the equation are as follows:
•
•
•
•
•
•
The ROCT value calculated shows the range of OCT resistance with the variation of temperature and VCCIO
RSCAL is the OCT resistance value at power-up.
.
ΔT is the variation of temperature with respect to the temperature at power up.
ΔV is the variation of voltage with respect to the VCCIO at power up.
dR/dT is the percentage change of RSCAL with temperature.
dR/dV is the percentage change of RSCAL with voltage.
OCT Variation after Power-Up Calibration
Table 10: OCT Variation after Power-Up Calibration for Cyclone V Devices
This table lists OCT variation with temperature and voltage after power-up calibration. The OCT variation is valid for a VCCIO range of 5% and a
temperature range of 0°C to 85°C.
