Abstract:
A method is provided for controlling a data transmission device that includes at least one fractional-sized subdriver. The method includes enabling at least one subdriver and driving a differential signal pair output. Also provided is a device with an output driver having a plurality of subdrivers where at least one subdriver is fractional-sized. The device also includes a de-emphasis portion configured to enable and disable the subdrivers. The device is configured to drive an output data signal. Also provided is a computer readable storage device encoded with data for adapting a manufacturing facility to create an apparatus such as the device. Also provided is an apparatus that includes an output driver with at least one fractional-sized subdriver and a de-emphasis portion configured to enable and disable the subdrivers of the output driver. The output driver is configured to drive a differential output data signal.
