ATCA Carrier for Two PCIe Modules
The ATC109 provides two PCIe x16 style right angle connectors that can accept any PCIe standard size module. Any of the PCIe x4 lanes can be configured as the up stream port. This allows the host (root complex) to be an external host connected to the ATC109 via front or rear. Further the host could reside on the PCIe slots that are on the ATC109.
This modular approach allows an AdvancedTCA chassis to utilize widely available high-end PCIe modules such as a PC graphics cards and capitalize on the economies of scale of the PC market.
