Abstract:
Methods of changing a centerline voltage of a data signal are described, along with apparatuses to change the centerline voltage. In one such method, portions of a termination circuit coupled to an output pin are selectively activated to change an impedance of the termination circuit to change the centerline voltage of the data signal driven to the output pin. One such apparatus includes pull-up impedances and pull-down impedances that can be activated to change the centerline voltage of the data signal. Additional embodiments are also described.
