Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel quantities. Confirm RoHS compliance status and environmental certifications prior to finalizing procurement orders. Ensure that the selected variant matches the required PCB footprint and thermal management specifications for the target application design.

Selection Notes

Select this component when a multi-port expansion solution is required for PCIe Gen 2 architectures. Evaluate the pinout compatibility with the host board layout, specifically the 196-ball LBGA configuration. Consider the power dissipation limits and thermal requirements relative to the enclosure environment. Verify that the supported lane widths and port configurations align with the system topology requirements.

Part Context

This component belongs to the PI7C9X2G series of packet switches from Diodes Incorporated. It serves as a bridge between upstream hosts and multiple downstream endpoints. The device facilitates signal distribution and protocol translation within complex PCIe networks. It is designed to replace discrete switching solutions, offering a compact form factor and reduced bill of materials for high-density designs.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified alternative part numbers. Ensure any substitute maintains identical pin assignments, voltage levels, and thermal characteristics. Verify that replacement components support the same PCIe Gen 2 specification and feature set.
