PI2EQX5864CZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5864CZFEX is a 4-lane (8 differential channels) PCIe Gen-2 signal conditioner operating at 5.0Gbps. It features programmable receiver equalization and transmitter de-emphasis to restore signal integrity over FR4 traces up to 30 inches. The device utilizes I2C configuration, supports 100-Ohm differential CML I/Os, and operates on a 1.2V±0.1V supply with 100mW power consumption per channel. It includes automatic receiver detection, loop-back modes, and signal detect support.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable receiver equalization and transmitter de-emphasis to compensate for signal attenuation and pattern-dependent jitter in high-speed data paths.
• Configured exclusively via the I2C interface, offering a compact solution compared to pin-strapped alternatives.
• Supports automatic receiver detection and electrical idle states per channel without requiring an external reference clock.

Signal Buffers, Repeaters, Splitters Applications

• Blade servers requiring signal integrity assurance across backplanes
• Storage servers and telecom equipment
• PCIe cables and desktop PCs with dual-graphics configurations

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified agents. Confirm the specific suffix matches the required package and tape-and-reel specifications. Request official datasheets and compliance documentation prior to purchase to ensure compatibility with system design requirements.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this model when I2C-only configuration is preferred over pin-strapped settings. It serves as a lower-cost alternative to the PI2EQX5804 while maintaining identical functional performance. Ensure the PCB layout accommodates the TQFN package dimensions and thermal requirements for sustained operation.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the Pericom PI2EQX58xx series of PCIe Gen-2 ReDrivers. It functions as a subset of the PI2EQX5804, distinguished primarily by its packaging and configuration method. The product line addresses signal degradation challenges inherent in 5.0Gbps differential signaling over standard PCB materials.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI2EQX5804 is the primary functional equivalent, differing only in pin configuration and package type. Verify that the replacement supports the necessary I2C interface if the original design relies on software-controlled settings rather than hardware straps.
