Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity using official manufacturer documentation or authorized distributor channels. Confirm that the specific ordering suffix matches the required package type and configuration options. Ensure compliance with RoHS standards and check for any end-of-life notices before finalizing procurement plans.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this model when a compact, cost-effective solution for extending PCIe Gen2 trace lengths is required. It is suitable for designs where I2C-based configuration is preferred over pin-strapping. Verify that the application environment supports the specified voltage range and thermal requirements for high-speed signal conditioning.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the Pericom PCIe Gen2 ReDriver family, specifically designed as a subset of the PI2EQX5804. It shares identical functional capabilities but utilizes a smaller 56-contact TQFN package. The primary distinction lies in its exclusive reliance on the I2C interface for configuration settings.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI2EQX5804 serves as a direct functional equivalent with expanded configuration options. Verify compatibility regarding package dimensions and I2C addressing if substituting within an existing design layout.
