Notes:
1. The ROCT value shows the range of OCT resistance with the variation of temperature and VCCIO
2. RSCAL is the OCT resistance value at power-up.
.
3. ΔT is the variation of temperature with respect to the temperature at power-up.
4. ΔV is the variation of voltage with respect to the VCCIO at power-up.
5. dR/dT is the percentage change of RSCAL with temperature.
6. dR/dV is the percentage change of RSCAL with voltage.
