Abstract: A system and method for efficient detection of Low Frequency Periodic Signaling (LFPS) input signals. A receiver receives two input differential signals that are LFPS input signals. The receiver increases the common-mode voltage for each of the two input differential signals and determines two polarity opposite differences between the level shifted intermediate differential signals. The differences are used to generate two series of relatively narrow pulses by comparisons with a given threshold. A wide continuous pulse is asserted when an initial pulse among the two series of pulses is detected. The wide continuous pulse is deasserted when a final pulse among the two series of pulses is detected. While the wide continuous pulse is asserted, control logic is awakened and performs a Universal Serial Bus (USB) protocol for processing data on the input differential signals.

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.
