PEX8114-BC13BI

Specialized Overview

The PEX8114-BC13BI is a PCI Express-to-PCI/PCI-X bridge manufactured by Broadcom Limited. It features four lanes of PCI Express connectivity and two ports for PCI or PCI-X bus interfaces. The device supports a maximum clock frequency of 133 MHz and operates within a voltage range of 1 V to 1 V. It is designed for surface mount installation and functions reliably between -40°C and +85°C.

Specialized Feature Summary

• Provides transparent bridging between PCI Express and legacy PCI/PCI-X architectures
• Supports forward and reverse operating modes for flexible system integration
• Includes integrated power management and hot-plug capabilities

Specialized Applications

• PCI Express adapter boards connecting to legacy PCI peripherals
• Motherboard expansion slots providing PCI-X connectivity via PCI Express
• PCI-X host systems supporting PCI Express expansion cards

Specialized Procurement Notes

Verify component authenticity through authorized channels as the part is discontinued. Confirm silicon revision BC compatibility with existing firmware. Check RoHS compliance status against current environmental regulations before procurement.

Specialized Selection Notes

Evaluate thermal requirements for the PBGA256 package in high-density designs. Ensure sufficient decoupling capacitors are placed near power pins to maintain signal integrity at 133 MHz operation. Verify that the target system architecture supports the required bridge mode configuration.

Specialized Part Context

This component belongs to the PLX Technology ExpressLane family, now under Broadcom. It serves as a critical interface solution for migrating legacy PCI/PCI-X devices to modern PCI Express platforms while maintaining protocol compatibility and performance standards.

Specialized Replacement Considerations

No direct public substitutes are confirmed. Evaluate newer Broadcom bridge controllers for functional equivalence. Verify pinout compatibility and register mapping differences during transition planning.
