37 / 82 page Chapter 2: Device Datasheet for Arria V Devices 2–9 Electrical Characteristics February 2012 Altera Corporation Arria V Device Handbook Volume 1: Device Overview and Datasheet OCT calibration is automatically performed at power up for OCT-enabled I/Os. Table 2–10 lists OCT variation with temperature and voltage after power-up calibration. Use Table 2–10 to determine the OCT variation after power-up calibration and Equation 2–1 to determine the OCT variation without recalibration. Table 2–10 lists the OCT variation after the power-up calibration. Pin Capacitance Table 2–11 lists the Arria V pin capacitance. Equation 2–1. OCT Variation Without Recalibration—Preliminary (1), (2), (3), (4), (5), (6) Notes to Equation 2–1: (1) The ROCT value calculated from Equation 2–1 shows the range of OCT resistance with the variation of temperature and VCCIO. (2) RSCAL is the OCT resistance value at power-up. (3) T is the variation of temperature with respect to the temperature at power up. (4) V is the variation of voltage with respect to the V CCIO 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. Table 2–10.
