PI7C9X130DNDE

Specialized Overview

The PI7C9X130DNDE is a PCI Express to PCI-X reversible bridge manufactured by Diodes Incorporated. It supports PCIe Base Specification 1.1 and PCI/PCI-X specifications, enabling bidirectional bridging between PCIe and legacy PCI/PCI-X domains. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 160-pin LFBGA package. Key electrical parameters include a maximum payload size of 512 bytes, support for up to 8 bus masters via two-level internal arbitration, and compatibility with 3.3V signals featuring 5V I/O tolerance.

Specialized Feature Summary

• Fully reversible architecture allowing dynamic configuration of PCIe as primary or secondary interface
• Supports transparent and non-transparent bridge modes for flexible system integration
• Integrated GPIO capabilities with four dedicated bidirectional pins and additional inputs/outputs when using external arbitration
• Comprehensive error handling including data poisoning, loopback, and advanced error reporting

Specialized Applications

• Legacy peripheral expansion in modern PCIe-based systems
• Industrial control systems requiring robust PCI/PCI-X connectivity
• Telecommunications infrastructure utilizing mixed protocol environments

Specialized Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels. Confirm the specific DNDE suffix matches design requirements. Ensure compliance with RoHS directives and relevant safety standards before implementation. Review the datasheet for absolute maximum ratings to prevent operational damage during procurement validation.

Specialized Selection Notes

Evaluate the requirement for reversible bridging versus fixed-direction alternatives. Consider the 160-pin LFBGA package constraints for PCB layout. Assess thermal management needs given the operating temperature range. Verify compatibility with existing PCI/PCI-X devices regarding voltage levels and signal integrity.
