PI7C9X2G304ELQZXAE

Specialized Overview

The PI7C9X2G304ELQZXAE is a PCI Express Gen 2 packet switch manufactured by Diodes Incorporated. It features three ports with four lanes per port, supporting data rates up to 5 Gb/s. The device operates on a single 1.1 V power supply within a 950 mV to 1.1 V range and dissipates 650 mW of power. It utilizes an aQFN-136 package (10x10 mm) for surface mount installation. The component supports a maximum clock frequency of 100 MHz and has a propagation delay of 6.5 ns. Operating temperatures range from -40°C to +85°C.

Specialized Feature Summary

• Supports PCIe Gen 2 protocol with 3-port, 4-lane architecture
• Integrates Transparent Mode configuration registers for system management
• Includes EEPROM interface and System Management Bus (SMBus) support
• Provides JTAG boundary scan capability for testing and verification

Specialized Applications

• PCIe packet switching in server infrastructure
• High-performance storage area networks (SAN)
• Industrial automation control systems

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure that the selected variant matches the required thermal and electrical characteristics for the target application environment.

Specialized Selection Notes

Select this component when a compact, low-power PCIe Gen 2 switch with three downstream ports is required. Verify compatibility with the host system's voltage requirements and ensure adequate thermal management solutions are implemented given the 650 mW power dissipation rating. Consider the aQFN-136 package dimensions during PCB layout planning.

Specialized Part Context

This part belongs to the ExtremeLo PCIe 2.0 Packet Switch family from Diodes Incorporated. It is designed to expand PCIe connectivity in space-constrained environments. The QZXAE suffix typically denotes specific packaging and tape-and-reel configurations compared to other variants in the same functional series.

Specialized Replacement Considerations
