Mini PCI Express Bus Extender

Disclosed is a method for a point-to-point extender between a mini PCI Express card and a computer platform. Benefits include testing and measuring mini PCI Express devices outside their original slots.

Background

The mini PCI Express board is a new board form factor which requires a new type of extender board. Currently, there is no mini PCI Express extender on the market. A mini PCI Express extender is necessary for any company developing or validating mini PCI Express devices. As the PCI Express and mini PCI Express expand and replace the standard PCI, there will be increased demands for a PCI Express extender.

General Description

The disclosed method is a point-to-point extender between a mini PCI Express card and a computer platform, and is designed to test and measure mini PCI Express devices (see Figure 1). The disclosed method has three main sections (see Figure 2):

§         a rigid printed circuit board (PCB) in a mini PCI Express form factor

§         a flexible differential cable to extend the bus away from the platform

§         another rigid PCB with a full mini PCI Express connection solution on it, as if it were the platform

The first section must be in the mini PCI Express Card form factor to be able to plug into the mini PCI Express connection on the platform. The electrical connection occurs through the two-sided edge card connector (i.e. Gold-Fingers). This section of the PCB also contains the 14 differential pair cable connector footprint. The mini PCI Express signals are routed on this PBC from the Gold-Finger to the cable connector (see Figure 3).

The second section is the flexible 14 differential pair cable through which the electrical traces (mini PCI Express signals)...
