US 5,334,962 A · High-speed data supply pathway systems

Abstract

The high speed data pathway system is used to convey data signals to integrated circuits connected to mother and daughter boards. The integrated circuits include a package and an integrated circuit chip carried by the package. An internal transmission line is carried by the package and coupled to the integrated circuit chip. The package includes both input and output connections for the internal transmission line. A high speed pathway is formed by serially connecting the internal transmission lines with external transmission lines to form a unified transmission medium. Advantageously, the internal transmission lines, external transmission lines and the connection between them have substantially corresponding characteristic impedances.

Claims7

Dependent claims

A very fast electrical data transmission pathway for connecting to at least one high speed integrated circuit comprising an integrated circuit chip carried by an integrated circuit package, said pathway comprising:

a plurality of differential transmission lines external to the integrated circuit package;
at least one continuous internal transmission line extending through said integrated circuit package;
means for connecting said integrated circuit chip to said internal transmission line;
and
means for connecting said internal transmission line in electrical series with at least two of said plurality of differential transmission lines.
