The PEX8114-BC13BI is a PCIe-to-PCI/PCI-X bridge from Broadcom, designed to provide connectivity between PCI Express-based systems and legacy PCI/PCI-X devices. This bridge is used when older PCI and PCI-X peripherals need to be integrated into a newer computing environment using a PCIe bus. It essentially allows older hardware to be used with modern computers.

Applications

• Industrial Automation: Connecting legacy control systems to modern computers.
• Data Acquisition: Bridging older data acquisition cards to new systems.
• Medical Imaging: Supporting older PCI/PCI-X based imaging equipment.
• Telecommunications Equipment: Connecting older telecom cards to newer servers.
• Embedded Systems: Enabling legacy peripheral support.

Features

• PCI Express to PCI/PCI-X Bridge: Transfers data between PCI Express and PCI/PCI-X buses.
• 32-bit and 64-bit PCI/PCI-X Support: Compatible with a variety of PCI and PCI-X devices.
• Transparent Operation: Simplifies system integration by allowing devices on either side of the bridge to operate as if directly connected.
• DMA Support: Enables Direct Memory Access for fast data transfers.
• Hot-Plug Support: Allows PCI/PCI-X cards to be inserted or removed while the system is running.
• Error Reporting: Provides detailed error information to facilitate debugging.

Benefits

• Legacy Hardware Compatibility: Extends the life of existing PCI/PCI-X devices.
• Cost Savings: Avoids the need to replace older peripherals when upgrading systems.
• Simplified Integration: Streamlines the process of connecting devices with different bus architectures.
• Improved Performance: DMA support enables high-speed data transfers.
• Increased Reliability: Hot-plug support and error reporting enhance system uptime.

Additional Details

The PEX8114-BC13BI functions as a transparent bridge, enabling seamless communication between PCI Express and PCI/PCI-X devices. This transparency simplifies system integration and reduces the need for custom drivers. It supports Direct Memory Access (DMA), which allows devices to transfer data directly to and from memory without involving the CPU, resulting in faster data transfer rates. The device also includes advanced error reporting features that help identify and resolve system issues quickly. These devices are usually packaged in a BGA (Ball Grid Array) for easy surface mounting.
