PI7C9X2G404SLBFDEX

Overview

The PI7C9X2G404SLBFDEX is a SlimPacket PCIe 2.0 packet switch manufactured by Diodes Incorporated, designed for high-speed data routing in PCI Express systems. It features one upstream port and four downstream ports, each supporting four lanes at transfer rates up to 5 GT/s. The device operates within an ambient temperature range of -40°C to +85°C and requires a supply voltage between 900 mV and 3.6 V, with typical operation at 3.3 V. It is housed in a 128-pin LQFP package and supports power dissipation up to 650 mW.

Feature Summary

• Supports PCI Express Gen 2 specifications with non-blocking switching capability
• Integrates a reference clock buffer for each downstream port
• Includes advanced error reporting and virtual channel arbitration
• Features EEPROM interface and System Management Bus (SMBus) support

Applications

• High-performance server and storage backplanes
• PCIe expansion chassis and riser cards
• Industrial computing and embedded systems requiring robust connectivity

Procurement Notes

Verify the component against official datasheet DS40068 Rev 2-2 to confirm authenticity. Ensure the ordering suffix matches the required packaging format, as variations exist between reel, cut tape, and tray options. Cross-reference the manufacturer part number with authorized distributor listings to validate current availability and compliance status.

Selection Notes

Select this component when designing systems that require expanding a single PCIe root complex into multiple endpoints. Confirm that the PCB layout accommodates the 128-pin LQFP footprint and thermal requirements. Verify that the application environment stays within the specified operating temperature range and voltage limits to ensure reliable performance.

Part Context

This part belongs to the PI7C9X2G404 family of SlimPacket switches from Diodes Incorporated. It serves as a direct replacement for legacy Pericom Semiconductor PCIe switches. The 'FDE' suffix indicates specific packaging and environmental qualifications compared to other variants in the series.

Replacement Considerations

PI7C9X2G404SLBFDE is a verified substitute offering identical electrical characteristics but packaged in trays instead of reels.
