Abstract
A device and method for calibrating a slew rate is disclosed. The slew rate may be for a driver of a bi-directional buffer. A driver outputs a signal having a frequency. A receiver is coupled to the driver. A frequency counter measures the frequency of the signal. A calibrated slew rate is determined by the frequency of a waveform of the signal. Different waveforms may be determined for the pull-up and pull-down calibrations.
