PI7C9X2G404SLBFDE

Overview

The PI7C9X2G404SLBFDEX is a SlimPacket PCIe 2.0 packet switch manufactured by Diodes Incorporated, designed for high-performance data routing in PCI Express systems. It features one upstream port and four downstream ports, each supporting four lanes of connectivity. The device operates on a single 3.3 V supply voltage and supports a maximum payload size of 512 bytes. It accommodates an operating temperature range from -40°C to +85°C and is housed in a 128-pin LQFP package.

Feature Summary

• Supports PCIe Gen 2.0 standard with non-blocking switching capability between ports.
• Integrates an EEPROM interface and System Management Bus (SMBus) for configuration and management.
• Includes advanced power management features such as Active State Power Management (ASPM) and L1/L0s state support.

Applications

• High-density server backplanes requiring multiple PCIe expansion slots.
• Storage area network (SAN) controllers and RAID subsystems.
• Industrial automation equipment utilizing PCIe-based communication protocols.

Procurement Notes
