Problems solved by technology

The resulting turns and transitions at the junction affect the integrity of the signal it transmits
So it becomes difficult to route transmission line traces in a way that achieves impedance uniformity and low signal loss
[0003] Therefore, it becomes difficult to properly design signal transmission lines in the board or backplane to meet the required crosstalk and loss in high speed applications
It is desirable to use economical circuit board materials such as FR4, but when the data transmission rate reaches 10Gbps, the performance of FR4 drops sharply, which makes designers use more expensive circuit board materials and increases the overall cost of the equipment using the circuit board. cost

Abstract

A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a chip, or processor mounted on a circuit board to a backplane. The bypass cable assembly has a structure that maintains the geometry of the cable in place from the chip to the connector and then through the connector. The connector includes a plurality of conductive terminals and shield members arranged within an insulative support frame in a manner that approximates the structure of the cable so that the impedance and other electrical characteristics of the cable may be maintained as best is possible through the cable termination and the connector.

Description

technical field [0001] The present application relates generally to cable interconnect systems, and more particularly to bypass cable interconnect systems that transmit high speed signals from a chip or processor to a backplane with low loss. Background technique [0002] Traditional cable interconnection systems exist in electronic equipment (such as routers, servers, etc.) and are used to form a connection between a main chip component (mounted on a printed on the signal transmission lines between the circuit boards). The transmission lines typically take the form of a plurality of conductive traces etched or otherwise formed on or as part of the printed circuit board. These traces extend between the chip component and a connector that provides a connection between one or more external plug connectors and the chip component. Circuit boards are usually formed from an inexpensive material known as FR-4. However, FR-4 is known to cause increased losses in high speed signal...
