Abstract
A method is provided for controlling a data transmission device. The method includes providing a reference voltage to the common mode driver and putting the data transmission device in a low power state. The method also includes driving a differential signal pair output from the common mode driver during a portion of the low power state. Also provided is a device that includes a data output driver portion configured to drive an output signal at a common mode voltage and a data output driver portion configured to drive an output signal at a differential voltage level during at least a portion of time when the device is not in a low power state. Also provided is a computer readable storage device encoded with data for adapting a manufacturing facility to create the device. Also provided is an apparatus configured to perform the method.
