PCI2050PDVG4

Specialized Overview

The Texas Instruments PCI2050PDVG4 is a lead-free, industrial-grade PCI-to-PCI bridge compliant with the PCI Local Bus Specification and PCI-to-PCI Bridge Specification 1.1. It connects two 32-bit, 33-MHz PCI buses to overcome electrical loading limits of ten devices per bus. The device features independent read/write buffers, burst-mode transfers, and internal two-tier arbitration for up to nine secondary bus masters. It supports CompactPCI hot-swap functionality, PCI Power Management 1.0/1.1, and operates within an extended temperature range.

Specialized Feature Summary

• Supports concurrent bridged transactions on both primary and secondary buses
• Provides internal two-tier arbitration for multiple secondary bus masters
• Includes CompactPCI hot-swap extended capability for system reliability
• Features universal PCI interfaces compatible with 3.3-V and 5-V signaling

Specialized Applications

• Multifunction CompactPCI cards requiring hierarchical bus expansion
• Adapting single-function cards to meet CompactPCI hot-swap compliance requirements
• Systems requiring isolation of PCI bus electrical loading limits

Specialized Procurement Notes

Verify that the ordering suffix G4 indicates lead-free manufacturing status as specified in the datasheet. Confirm the package type matches the required 208-terminal PDV form factor. Ensure the component meets the specific industrial temperature range requirements for the target application environment before finalizing procurement.

Specialized Selection Notes

Select this component when designing systems that require connection between two 32-bit PCI buses operating at frequencies up to 33 MHz. It is suitable for applications needing support for up to nine secondary bus masters with internal arbitration. Consider this part for designs requiring CompactPCI hot-swap capabilities or strict adherence to PCI Power Management specifications.

Specialized Part Context

The PCI2050 family includes variants such as the PCI2050PDV (commercial grade) and PCI2050IPDV (industrial grade). The PCI2050PDVG4 represents the lead-free version of the commercial-grade 208-terminal QFP package. Other package options include the 209-terminal MicroStar BGA formats like GHK and ZHK.
