PI7C9X2G304SLAFDE

Specialized Overview

The PI7C9X2G304SLAFDE is a PCI Express 2.1 compliant packet switch manufactured by Diodes Incorporated under the SlimLine family. It features one upstream port supporting x1 or x2 lanes and two downstream ports, each with x1 lane capability. The device operates within a supply voltage range of 900 mV to 1.1 V and supports an industrial temperature range from -40°C to +85°C. It utilizes a 128-pin LQFP package measuring 14mm x 14mm. The switch provides non-blocking full-wired switching at 32 Gbps when all four lanes are enabled, with typical power dissipation of 0.65 W in L0 mode and 0.17 W in L1 mode.

Specialized Feature Summary

• Non-blocking full-wired switching capability at 32 Gbps when all four lanes are enabled
• Integrated 100 MHz clock buffer for each downstream port
• Supports Data Poisoning, End-to-End CRC, Advanced Error Reporting, and IEEE 1149.6 JTAG interface
• Advanced power management including Link Power Management (L0, L0s, L1, L2, L2/L3Ready, L3) and Device State Power Management (D0, D3Hot, D3Cold)

Specialized Applications

• Wireless AP/Router and Wire/Wireless Tele/data communication systems
• Embedded systems, Set-top boxes, and Industrial control applications
• NAS/Storage, Printer/MFP, and Peripheral devices

Specialized Procurement Notes

Verify that the ordering suffix 'FDE' corresponds to the specific tape and reel packaging configuration as indicated by the datasheet note regarding the 'X' suffix. Confirm RoHS compliance and green manufacturing status directly with the manufacturer documentation. Ensure the component meets the required industrial temperature range specifications for the intended deployment environment.

Specialized Selection Notes

Select this component when a compact PCIe 2.1 expansion solution is required for power-sensitive platforms. The SlimLine architecture offers flexibility for fan-out from PCH, ICH, IOH, embedded MCUs, or FPGAs. Consider the integrated clock buffer and advanced power-saving features like ACS and SR-IOV support if system complexity and energy efficiency are primary design constraints.
