PI7C9X2G404SLAFDEX

Overview

The PI7C9X2G404SLAFDEX is a SlimPacket PCIe 2.0 packet switch manufactured by Diodes Incorporated, designed for high-performance data routing in complex systems. It features four downstream ports and one upstream port, 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 utilizes a 128-pin LQFP package. Key electrical parameters include a maximum power dissipation of 650 mW and a supply voltage range from 900 mV to 3.6 V. It supports advanced features such as non-blocking architecture, 512-byte payload sizes, and integrated clock buffers.

Feature Summary

• Supports PCI Express Gen 2 specifications with four-lane per port connectivity
• Features a non-blocking internal architecture for simultaneous data transmission
• Includes integrated reference clocks and clock buffers for each downstream port
• Provides comprehensive error reporting and management capabilities

Applications

• High-density server backplanes requiring scalable I/O expansion
• Storage area networks (SAN) and enterprise storage controllers
• Industrial automation systems operating in extended temperature environments
• Telecommunications infrastructure equipment needing reliable packet switching

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging type and moisture sensitivity level. Ensure that the procurement channel is authorized to maintain product integrity and traceability. Cross-reference the component marking with the datasheet pinout to prevent installation errors during assembly.

Selection Notes

Select this component when designing systems requiring multiple PCIe endpoints connected to a single host controller. Consider the thermal performance requirements given the 650 mW power dissipation rating. Evaluate the PCB layout constraints associated with the 128-pin LQFP package dimensions and pitch specifications.

Part Context
