PI7C9X2G612GPCNJEX

Overview

The PI7C9X2G612GPCNJEX is a PCI Express Gen 2 packet switch manufactured by Diodes Incorporated. It provides six downstream ports and twelve lanes for high-speed data routing. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 196-ball LBGA package. It supports PCIe Base Specification Revision 2.0, accommodating link speeds up to 5.0 GT/s per lane. The component integrates comprehensive configuration registers, power management capabilities, and error reporting mechanisms suitable for complex system architectures.

Feature Summary

• Supports six downstream ports with twelve total lanes for flexible topology expansion
• Integrates advanced transaction layer features including virtual channel arbitration and flow control
• Includes EEPROM interface and SMBus/I2C support for automated configuration and system management

Applications

• High-performance server backplanes requiring multi-port connectivity
• Storage area network (SAN) infrastructure switches
• Industrial automation systems demanding reliable PCIe interconnectivity

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprint designs before procurement. Confirm RoHS compliance status through current datasheet revisions. Validate supply chain sources to guarantee authentic components from authorized distributors.

Selection Notes

Select this component when a six-port, twelve-lane PCIe Gen 2 switching solution is required. Consider the 196-ball LBGA package constraints during mechanical design. Evaluate thermal dissipation requirements based on the specified operating temperature range. Compare against alternative port counts if fewer lanes are sufficient for the target application architecture.

Part Context

This part belongs to the PI7C9X2G series of green package family switches designed by Diodes Incorporated. It succeeds earlier Pericom Semiconductor products following corporate integration. The series focuses on providing robust packet switching capabilities for enterprise and industrial environments while maintaining backward compatibility with established PCIe standards.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains identical lane counts and port configurations. Cross-reference electrical characteristics and package dimensions to ensure seamless integration without redesigning the host board layout.
