PI7C9X2G612GPNJEX

Overview

The PI7C9X2G612GPNJEX is a PCI Express Gen 2 packet switch manufactured by Diodes Incorporated. It provides six downstream ports and twelve lanes for high-speed data routing. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 196-ball LBGA package. It supports PCIe specifications including power management, error reporting, and virtual channels. Configuration is managed via EEPROM or I2C/SMBus interfaces, allowing flexible system integration.

Feature Summary

• Supports six-port, twelve-lane PCI Express Gen 2 topology
• Integrates transparent mode configuration registers for system control
• Includes dedicated EEPROM interface with auto-mode access capability
• Features System Management Bus (SMBus) and I2C slave interface support

Applications

• High-performance server backplanes requiring multi-lane connectivity
• Storage area network (SAN) infrastructure switches
• Industrial computing systems demanding wide operating temperatures

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel quantities. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Ensure the component matches the required pinout and electrical characteristics for the target application design.

Selection Notes

Select this component when a six-port, twelve-lane PCIe Gen 2 switching solution is required. Verify that the 196-ball LBGA package fits the PCB layout constraints. Check compatibility with existing EEPROM configurations and ensure the I2C/SMBus interface aligns with the host controller capabilities.

Part Context

This part belongs to the PI7C9X2G family of PCI Express packet switches from Diodes Incorporated. The family includes variants with different port counts and lane configurations. The PI7C9X2G612GP serves as the base model designation for the six-port architecture described in the official datasheet.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the same product family. Verify pin-to-pin compatibility and register mapping before replacing the component in an existing design.
