Abstract

An improved driver for differentially driving a differentially conducting cable (e.g., for Ethernet) minimizes the output offset signal coupled to the cable when the driver is idle. When driven to an idle state, the driver provides a shaped output which transitions to a quiescent output level in a manner which eliminates output signal common mode step change and consequently reduces signal distortion on the cable due to reflection of the step change.
