摘要：
A circuit and method for improving signal integrity characteristics of a non-full rate transmitter are disclosed herein. The circuit comprises an actuator block having an input for receiving a differential clock signal, the differential clock signal comprising a positive clock signal and a negative clock signal, the actuator configured to adjust a difference between the positive and negative clock signals; a sensing block, for sensing a difference between positive and negative signals of a differential signal, the differential signal being related to the clock signal; and a calibration block for providing a control signal to the actuator based on the sensed difference between the positive and negative signals.
