Electrical Characteristics
Use the following with Equation 1â1:
â RSCAL is the OCT resistance value at power up.
â ïT is the variation of temperature with respect to the temperature at power up.
â ïV is the variation of voltage with respect to the VCCIO at power up.
â dR/dT is the percentage change of RSCAL with temperature.
â dR/dV is the percentage change of RSCAL with voltage.
Table 1â14 lists the OCT variation with temperature and voltage after power-up
calibration for Arria II GX devices.
