PI2EQX5804DNJE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5804DNJE is a four-lane, 5.0Gbps PCIe Gen-2 signal conditioner manufactured by Diodes Incorporated under the Pericom brand. It features eight CML differential input/output pairs designed to restore signal integrity over FR4 trace lengths up to 30 inches. The device operates at a supply voltage of 1.2V ± 0.1V with low power consumption of 100mW per channel. Configuration options include pin-strapped settings or I2C interface control. It supports automatic receiver detection, loop-back modes, and electrical idle signaling without requiring an external reference clock.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable receiver equalization and transmitter de-emphasis to compensate for signal attenuation and inter-symbol interference.
• Supports automatic receiver detection and control to manage link establishment processes dynamically.
• Includes loop-back and mux/demux modes for testing and diagnostic purposes during system validation.

Signal Buffers, Repeaters, Splitters Applications

• Blade servers requiring signal integrity assurance across long backplanes
• Storage servers and data/telecom infrastructure equipment
• PCIe cables and desktop PCs utilizing dual-graphics configurations

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels. Confirm package type matches the 100-ball LFBGA specification. Check RoHS compliance status against current environmental regulations. Validate that configuration pins are set correctly for the intended application mode before installation.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending PCIe Gen-2 traces beyond standard limits on FR4 substrates. Ensure the design accommodates the 1.2V supply requirement. Consider the 100-ball LFBGA footprint constraints during PCB layout. Verify that the application does not require the specific subset features found in the PI2EQX5864 variant.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI2EQX5804/5864 family of PCIe Gen-2 ReDrivers developed by Pericom Semiconductor, now part of Diodes Incorporated. These devices address signal degradation issues inherent in high-speed serial links by actively conditioning signals to meet PCIe specifications.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI2EQX5864 serves as a functional equivalent with identical performance but utilizes a 56-contact TQFN package and relies exclusively on I2C configuration. Verify package compatibility and configuration method differences before substitution.
