Electrical Characteristics
Use the following with Equation 1–1:
■ R_SCAL is the OCT resistance value at power up.
■ T is the variation of temperature with respect to the temperature at power up.
■ V is the variation of voltage with respect to the V_CCIO at power up.
■ dR/dT is the percentage change of R_SCAL with temperature.
■ dR/dV is the percentage change of R_SCAL with voltage.
Table 1–14 lists the OCT variation with temperature and voltage after power-up
calibration for Arria II GX devices.
