PI2EQX5804DNJEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5804DNJEX 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 with a Vcc supply range of 1.2V ± 0.1V and consumes approximately 100mW per channel. Configuration options include pin-strapped settings or I2C interface control. Key technical capabilities include programmable receiver equalization, programmable transmitter de-emphasis and amplitude adjustment, automatic receiver detection, loop-back modes, and electrical idle support.

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 without requiring an external reference clock.
• Features low-power operation with dedicated standby mode and per-channel signal detect functionality.

Signal Buffers, Repeaters, Splitters Applications

• Blade servers requiring signal integrity assurance across long backplanes
• Storage servers and data/telecom equipment
• PCIe cables and desktop PCs with 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 datasheet revisions for configuration differences between pin-strapped and I2C variants. Ensure environmental compliance documentation aligns with project requirements.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending PCIe Gen-2 traces beyond standard limits on FR4 substrates. Compare against the PI2EQX5864 if a smaller TQFN package is required, noting that the 5864 relies exclusively on I2C configuration. Evaluate power consumption constraints relative to the 100mW per channel rating during active operation.

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 at both ends of the transmission path.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI2EQX5864 serves as a functional alternative with identical performance but utilizes a 56-contact TQFN package and requires I2C configuration only. Verify pinout compatibility and configuration method changes before substitution.
