Abstract:
Aspects disclosed in the detailed description include skew control for three-phase communication. A three-phase communication involves three signal branches. A signal skew may occur when one signal branch is being coupled to a common mode voltage while another signal branch is being decoupled from the common mode voltage. In this regard, in one aspect, an impedance mismatch is introduced in the signal branch being coupled to the common mode voltage to help shift a rightmost crossing of the signal skew leftward. In another aspect, a current source or a current sink is coupled to the signal branch being decoupled from the common mode voltage to help shift a leftmost crossing of the signal skew rightward. By shifting the rightmost crossing leftward and the leftmost crossing rightward, it is possible to reduce the signal skew, thus leading to reduced jitter and improved data integrity in the three-phase communication.
