PCI2050BIPDVG4

Specialized Overview

The PCI2050BIPDVG4 is a PCI-to-PCI bridge controller manufactured by Texas Instruments. It provides a high-performance connection path between two Peripheral Component Interconnect (PCI) buses, supporting a maximum bus frequency of 66 MHz. The device operates with 3.3V core logic and features a universal PCI interface compatible with both 3.3V and 5V signaling environments. It utilizes advanced submicron CMOS technology for low power consumption. The component is housed in a 208-lead Plastic Dual Vertical (PDV) package.

Specialized Feature Summary

• Supports simultaneous bridging transactions across two independent 32-bit, 66 MHz PCI bus traffic paths.
• Includes internal two-level arbitration for up to nine secondary bus masters, with support for external arbitration.
• Features pipeline architecture for burst data transfers to maximize bidirectional data throughput.
• Provides CompactPCI hot-plug extension capabilities for enhanced system flexibility.

Specialized Applications

• Creating hierarchical bus structures to overcome electrical load limits on standard PCI buses.
• Implementing multi-function compact PCI cards requiring high-speed interconnectivity.
• Adapting single-function cards to meet CompactPCI hot-plug compliance requirements.

Specialized Procurement Notes

Verify the specific suffix IPDV against official Texas Instruments documentation to confirm the exact package type and tape-and-reel configuration. Ensure the component meets RoHS standards if required by your manufacturing process. Cross-reference the full part number with the manufacturer's current datasheet to confirm availability and any potential obsolescence status before finalizing procurement plans.

Specialized Selection Notes

Select this component when designing systems that require bridging two separate PCI domains while maintaining high data throughput at 66 MHz. It is suitable for applications needing internal arbitration for multiple secondary masters. Consider the 208-lead PDV package constraints during PCB layout. Verify compatibility with 3.3V and 5V signal environments if mixing voltage levels is necessary.

Specialized Part Context

The PCI2050B series serves as a bridge solution within Texas Instruments' portfolio of interface controllers. It addresses the limitation of ten devices per PCI bus by enabling hierarchical bus topologies. This specific variant integrates the bridge functionality into a dense package suitable for complex motherboard or add-in card designs requiring robust PCI connectivity.

Specialized Replacement Considerations

The PCI2050B is the base model for this family. Check for other suffixes such as PPM or MicroStar BGA options if different packaging is required. No direct functional replacements are listed in public documentation; consider the PCI2040 or Intel 21150 series only if architectural differences are acceptable.
