Abstract
A method is provided for selecting at least one of a plurality of slew rate control settings based at least upon a speed of data transmission and receiving input data where the input data is received at the data transmission speed. The method also includes switching the received input data in accordance with the selected at least one of a plurality of slew rate control settings and sending output data at the data transmission speed. Also provided is data driver device that includes at least one activation portion comprising one or more slew rate controls, a voltage-mode driver portion and at least a first current-mode driver portion. Also provided is a computer readable storage device encoded with data for adapting a manufacturing facility to create the data driver device. Also provided is a system including the data driver device, a data storage device and a processor device.
