OCT Variation after Power-Up Calibration
Figure 1-1: Equation for OCT Variation Without Recalibration
e definitions for the equation are as follows:
• e 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 1-10: OCT Variation after Power-Up Calibration for Arria V Devices
is table lists OCT variation with temperature and voltage afer power-up calibration. e OCT variation is valid for a VCCIO range of 5% and a
temperature range of 0°C to 85°C.
