摘要
Multi-protocol driver slew rate calibration systems for calibrating slew rate control signal values are provided. Embodiments include generating, by a first phase rotator, a first clock signal; generating, by the second phase rotator, a second clock signal; initially setting, by a calibration controller, phase selector amounts such that the first clock signal is delayed relative to the second clock signal; determining whether the first clock signal is delayed relative to the second clock signal; if the first clock signal is delayed, changing the second phase selector amount; and if the first clock signal is not delayed, using the first clock signal and the second clock signal to calibrate values of control signals provided to control a slew rate of a calibration clock delay line such that the slew rate of the calibration clock delay line substantially matches a target slew rate.
