1. A device, comprising:
a signal generating circuit configured to generate a pair of differential signals including a first voltage signal and a second voltage signal that have a slew rate
a comparator circuit configured to output an enabling signal according to a relative position between an eye crossing point of the pair of differential signals and an edge of a reference clock; and
a control circuit coupled between the signal generating circuit and the comparator circuit and configured to generate at least one control signal according to the enabling signal for controlling the signal generating circuit which changes according to the at least one control signal the slew rate of the first voltage signal and the second voltage signal.
