Abstract
Example embodiments of the present disclosure relate to a line driver apparatus. In some example embodiments, an apparatus is provided. The apparatus includes a capacitive feed-through module and a driving module. The capacitive feed-through module includes a first pre-driver operable to receive input differential signals and delayed signals of the input differential signals, generate first drive signals from the input differential signals and the delayed signals, and equalize the first drive signals. The capacitive feed-through module also includes a capacitance reducing module arranged between the first pre-driver and transmission lines and operable to reduce parasitic capacitance at the transmission lines in response to the first drive signals. The driving module is coupled to the transmission lines and operable to generate output differential signals from the input differential signals for transmission on the transmission lines.
