ABSTRACT:
A line driver apparatus includes a peak detector operable to receive a data signal and output a first logic signal when the data signal is below a threshold value and output one of a plurality of alternate logic signals when the data signal exceeds the threshold value. The peak detector includes a signal magnitude calculator operable to calculate an amount by which the data signal exceeds the threshold value. The line driver apparatus also includes an amplifier operable to receive a filtered analog data signal and one of a time-delayed first logic signal and one of a time-delayed alternate logic signal, wherein the amplifier operates at a first voltage level upon receiving the time-delayed first logic signal, and the amplifier operates at a voltage level that is increasing toward one of an alternate voltage level upon receiving the time-delayed second logic signal.
