PCI2050GHK

Specialized Overview

The Texas Instruments PCI2050GHK is a PCI-to-PCI bridge IC designed to connect two peripheral component interconnect buses. It operates at clock rates up to 33 MHz with a 32-bit data bus width. The device utilizes a 209-terminal MicroStar BGA package and supports universal PCI interfaces compatible with both 3.3-V and 5-V signaling environments. It features an operating temperature range of 0°C to 70°C.

Specialized Feature Summary

• Supports CompactPCI hot-swap functionality for multifunction cards
• Provides internal two-tier arbitration for secondary bus masters
• Enables concurrent bridged transactions on both buses

Specialized Applications

• Creating hierarchical buses to overcome electrical loading limits
• Adapting single-function cards to hot-swap compliance
• Connecting peripheral devices across separate PCI segments

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm voltage tolerance, temperature grade, and package type. Confirm RoHS status and lead-free availability through authorized channels before procurement.

Specialized Selection Notes

Select this model when a 209-terminal MicroStar BGA package is required for space-constrained designs. Ensure system requirements align with the 0°C to 70°C commercial temperature range and 33 MHz maximum clock speed specifications.

Specialized Part Context

This component belongs to the PCI2050 family of PCI-to-PCI bridges from Texas Instruments. It shares core architectural features with other variants in the series, differing primarily in package style and operating temperature specifications.

Specialized Replacement Considerations

The PCI2050IGHK serves as the industrial temperature variant within the same package family. Verify pin compatibility and thermal requirements when considering alternative packages such as the PDV QFP.
