PEX8114-BD13BIG

Specialized Overview

The PEX8114-BD13BIG is a high-performance bridge IC manufactured by Broadcom (formerly PLX Technology). It facilitates migration from legacy PCI and PCI-X interfaces to the PCI Express architecture. The device features four integrated 2.5 Gbps SerDes lanes, supporting scalable x1, x2, or x4 link widths with full-duplex operation. It operates on a 1.0 V core supply voltage and supports PCI-X modes at 66, 100, and 133 MHz for 64-bit data buses. The component is housed in a 256-pin Plastic BGA package measuring 17mm x 17mm. It functions within an industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports forward and reverse transparent bridging between PCI Express and PCI/PCI-X domains
• Integrates four 2.5 Gbps SerDes for flexible lane scaling and automatic lane reversal
• Includes advanced error reporting, end-to-end CRC, and hot-plug capabilities
• Operates with low power consumption without requiring external heat sinks

Specialized Applications

• Migrating legacy PCI and PCI-X systems to PCI Express architectures
• High-performance server and storage controller designs
• Industrial embedded systems requiring robust bus bridging

Specialized Procurement Notes

Verify authenticity through authorized distributors as the component is discontinued. Check for lead-free RoHS compliance markings on the package. Confirm the specific suffix indicates the correct manufacturing lot and material composition. Request original manufacturer documentation to validate part history and change notices prior to integration into new designs.

Specialized Selection Notes

Select this component when migrating existing PCI/PCI-X peripherals to PCI Express platforms. Ensure the design accommodates the 256-pin BGA footprint and 1.0V core voltage requirements. Verify that the target application supports the specified industrial temperature range and utilizes compatible EEPROM configuration methods for system initialization.

Specialized Part Context

This part belongs to the PLX Technology ExpressLane family, now managed under Broadcom. It serves as a bridge solution for connecting older peripheral buses to modern serial interconnects. The device was widely used in enterprise infrastructure before being superseded by newer generations of PCIe switches and bridges.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in verified sources. Designers should consult official Broadcom discontinuation notifications for recommended alternative components or contact authorized distributors for current equivalent offerings.
