Specialized Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and environmental rating. Ensure compliance with RoHS directives and check for any applicable export control classifications before finalizing procurement orders.

Specialized Selection Notes

Select this component when a reversible bridge between PCIe and legacy PCI buses is required. Verify that the 128-pin LQFP package fits the available PCB footprint. Ensure the design accommodates the specified operating temperature range and voltage requirements for reliable operation in industrial or commercial environments.

Specialized Part Context

This part belongs to the PI7C9X series of interface ICs produced by Diodes Incorporated, formerly Pericom Semiconductor. The series focuses on providing robust connectivity solutions between different bus standards. This specific model addresses the need for flexible bridging in systems where bidirectional communication between modern and legacy interfaces is necessary.

Specialized Replacement Considerations

Check for updated revisions within the same PI7C9X family. Verify pin compatibility if substituting with other models in the series. Ensure that any alternative components maintain the same package outline and electrical characteristics to avoid redesigning the host board.
