Additional Details:

The PEX8114-AA13BES bridge is typically available in a BGA (Ball Grid Array) package. It requires a 3.3V power supply. The device supports both upstream and downstream traffic between the PCI/PCI-X and PCIe buses. It includes configurable options for address translation, interrupt routing, and error handling. The datasheet should be consulted for complete electrical characteristics, timing diagrams, and pinout information. Proper decoupling and thermal management are essential for reliable operation. Software drivers are typically required for proper operation of the bridge.
