Abstract
According to at least one example embodiment a two phase calibration approach is employed for calibrating an input/output interface having multiple single-ended receivers. During a first phase, amplifier offset calibration is applied to each of the multiple single-ended receivers. During a second phase, reference voltage calibration is applied to a single-ended receiver of the multiple single-ended receivers to determine a calibration reference voltage value. The calibration reference voltage value is then employed in each of the multiple single-ended receivers during an active phase of the input/output interface.
