PI7C9X2G312GPBNJEX

Overview

The PI7C9X2G312GPBNJEX is a PCI Express Gen 2 packet switch manufactured by Diodes Incorporated. It features three ports with a total of twelve lanes, comprising one upstream port and two downstream ports, each supporting x4 operation. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 196-pin LBGA package measuring 15mm x 15mm. Typical power dissipation in L0 normal mode is 1.3 W, including the integrated clock buffer. The component supports a maximum payload size of 512 bytes and provides a typical latency of 150ns for unblocked packets.

Feature Summary

• Supports flexible link configurations with one x4 upstream port and two x4 downstream ports.
• Integrates proprietary GreenPacket technology for advanced power savings and idle state management.
• Provides comprehensive error handling through Data Poisoning, End-to-End CRC, and Advanced Error Reporting.
• Enables peer-to-peer switching between downstream ports with support for Access Control Service.

Applications

• Network Attached Storage (NAS) and storage systems
• Server infrastructure and Host Bus Adapters (HBA)
• Embedded systems and industrial control platforms
• Wired and wireless networking equipment

Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. The 'X' suffix indicates tape and reel packaging, while other suffixes may denote different quantities or formats. Confirm the specific part number against the manufacturer's official documentation to ensure compatibility with the intended application requirements.

Selection Notes

Select this component when a compact PCIe Gen 2 solution with three ports is required. Ensure the design accommodates the 196-pin LBGA footprint and thermal constraints associated with the specified power dissipation. Verify that the system architecture aligns with the supported voltage levels and interface specifications defined in the datasheet.

Part Context

This component belongs to the GreenPacket family of PCI Express switches from Pericom Semiconductor, now part of Diodes Incorporated. The family focuses on low-power, lead-free solutions designed for high-performance embedded and networking applications. The PI7C9X2G312GP variant specifically addresses needs for scalable connectivity in storage and server environments.

Replacement Considerations

Check for updated revisions within the same PI7C9X2G series. Verify pinout compatibility if considering alternative lane counts or port configurations from the manufacturer's portfolio.
