Abstract: Method and system for adaptive signal equalizing with alternating boost and amplitude controls. In accordance with one exemplary embodiment, data signal boost control is based on measured equalized and sliced data signal energies within a bandwidth disposed about a higher frequency, while sliced data signal amplitude control is based on measured equalized and sliced data signal energies within a bandwidth disposed about a lower frequency.

Abstract: System and method for adaptive signal equalizing in which overlapping data signal equalization paths provide cumulative data signal equalization to provide multiple equalized data signals having different available amounts of equalization. Signal slicing circuitry slices the equalized data signals to provide multiple sliced data signals, from which the sliced data signal selected as an output data signal is dependent upon the data rate of the incoming data signal.

Abstract: Power management for a computer system and device is accomplished by implementing two separate power modes in a serially-connected device, and selecting from the two power modes depending on the state of a receiver in the device. A signal detector within the receiver is connected to a serial interface port of the device to detect the presence of an input signal. A power controller selects a first power mode for the device when the signal detector detects the input signal and a second power mode for the device when the input signal is not detected by the signal detector.
