device, network component, and method for improving the power efficiency of a line controller

摘要

An line driver including a delay circuit, a DAC, a filter circuit, a peak predictor, a peak detector; and a control interface logic; the line driver further comprising a long timing delay circuit and a short timing delay circuit; wherein the filter circuit is configured to amplify an analog signal, and wherein the long timing delay circuit and a short timing delay circuit may be coupled in parallel to the peak detector and a control interface logic; the long timing delay circuit and the short timing delay circuit introduce a relatively long time delay and a relatively short delay, respectively, to signal on a control path.
