PI2EQX4401DZFE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX4401DZFE is a low-power, PCI-Express compliant signal re-driver manufactured by Diodes Incorporated. It supports one high-speed PCI-Express lane operating at 2.5Gbps. The device features adjustable transmitter de-emphasis and amplitude, as well as adjustable receiver equalization to optimize performance across various physical mediums. It includes a spread spectrum reference clock buffer output and input signal level detect with output squelch functionality. The component operates on a VDD supply voltage range of 1.8V ±0.1V and is housed in a 36-pad TQFN (ZF36) package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Programmable equalization, amplification, and de-emphasis via four selection bits to reduce inter-symbol interference
• Integrated low-level input signal detection and output squelch function for both channels
• Built-in differential clock buffer for test and system requirements independent of data channels
• Low power standby mode operated by a Bus Enable pin

Signal Buffers, Repeaters, Splitters Applications

• PCI-Express signal re-driving between Protocol ASICs and switch fabrics
• Signal extension across backplanes
• Extending signals across distant data pathways on user platforms

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZFE against official manufacturer documentation to confirm the package type and environmental compliance status. Ensure that the procurement channel provides valid traceability for the Diodes Incorporated brand. Cross-reference the datasheet revision date to confirm compatibility with current design specifications before finalizing orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring a single-lane PCI-Express repeater with integrated equalization capabilities. Consider the 36-pad TQFN package constraints and the 1.8V ±0.1V power supply requirement. Evaluate the need for the integrated clock buffer and signal detect features against alternative discrete solutions to determine if this integrated approach meets the board space and power budget goals.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI2EQX4401 series of PCI-Express compliant signal re-drivers. It is designed to maintain signal integrity over lossy transmission media. The device integrates both receiver equalization and transmitter de-emphasis control into a single compact package, simplifying the design process for high-speed serial interfaces compared to using separate components.
