Description.
The patent families P26, P27 and P28 are mainly intended to be applied to the ZXtalk techniques for the reduction of internal crosstalk and echo in electrical interconnections such as the one used in a system in package (SiP), a multi-chip module (MCM) or a printed circuit board (PCB). The ZXtalk method improves the performance of links used to obtain m transmission channels using an interconnection having m transmission conductors. The link features a low crosstalk between the transmission channels, in spite of a narrow spacing between the transmission conductors. The link also uses fewer conductors than m differential links.
A short presentation of the ZXtalk method is available in the Section 3 of this page. Several peer-reviewed technical articles published on this subject matter may be downloaded here. Excem also offers two Seminars and a free electronic book presenting the technical background for assessing and implementing this technology.
For a conference with technical experts, please contact us. We can also provide several reports relating to these inventions.
