Network communications using sine waves

Abstract

A system comprising the following elements. An ethernet controller circuit for generating ethernet data signals. An isolation circuit coupled to receive the ethernet data signals and for generating ethernet output signals. The ethernet output signals including primarily a first sine wave signal, a second sign wave signal, and a set of signals. The first sine wave signal is at a frequency approximately equal to the frequency of the ethernet data signals. The second sine wave signal is at a frequency approximately one half the frequency of the first sine wave signal. The third set of signals is for transitioning between said first sine wave signal and said second sine wave signal. In this embodiment, the high frequency components of the output signals is significantly reduced, which results in reduced electromagnetic interference from the system.
