Interposer for peripheral component interconnect express generation 4

Abstract:

An interposer for a Peripheral Component Interconnect Express (PCI-e) host device and a PCI-e target device may include a plurality of linear repeaters to perform repetition or crosspoint switching of signals en route from the PCI-e host device to the PCI-e target device or from the PCI-e target device to the PCI-e host device; and a plurality of interposer components, the plurality of interposer components to receive the signals from the plurality of linear repeaters or provide the signals to the plurality of linear repeaters, and at least one interposer component, of the plurality of interposer components, being associated with a resistance of at least 50 ohms. Thus, the interposer may be compliant with a PCI-e protocol, such as the PCI-e Gen 4 protocol.
