Abstract
An integrated circuit may include at least a first replica driver stage coupled between a reference impedance input and a first power supply node and having a first programmable driver impedance set by a first driver configuration value in the same manner as a first output driver section of the integrated circuit. At least a first replica input termination stage may be coupled between the reference impedance input and the first power supply node and having a first programmable termination impedance set by a first termination configuration value in the same manner as a first input termination section of the integrated circuit. An impedance programming circuit may generate at least the first driver configuration value and the first termination configuration value in response to a potential at the reference node.
