PI3EQX2004ZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX2004ZHEX is a high-performance 10Gbps four-lane USB 3.2 Gen 2x2 linear ReDriver manufactured by Diodes Incorporated. It operates on a single 3.3V supply voltage and supports data rates of 10 Gbps across four differential signal pairs. The device features 100Ω differential CML I/Os, automatic receiver detect, and slave I2C support up to 1MHz. It is housed in a 42-contact Very Thin Quad Flat No-Lead (TQFN) package with dimensions of 3.5 x 9mm.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable equalization and flat gain to optimize performance over various physical mediums by reducing inter-symbol interference.
• Features four independently controlled channels for equalization, flat gain, and swing signal outputs.
• Supports two 100Ω differential CML data I/Os between protocol ASICs and switch fabrics or distant data pathways.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZHEX confirms the TQFN-42 package and tape/reel packaging format. Confirm RoHS 3 compliance and green device status regarding halogen and antimony limits if required for regulatory adherence. Check for automotive qualification requirements such as AEC-Q100 if intended for vehicle applications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for designs requiring 10Gbps USB 3.2 Gen 2x2 signal integrity enhancement. Ensure the system provides a stable 3.3V single supply voltage. Verify that the PCB layout accommodates the 3.5 x 9mm TQFN footprint and that I2C bus speed requirements do not exceed 1MHz for slave control operations.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3EQX series of ReDrivers designed for high-speed serial links. It specifically targets USB 3.2 protocols, offering linear equalization capabilities distinct from other series members that may support PCIe or SATA standards. The ZH suffix denotes the specific 42-pin TQFN package variant within this product line.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Consult official substitution guides for compatible parts within the PI3EQX family. Verify pinout compatibility and electrical specifications before replacing with variants like the PI3EQX1004 or PI3EQX25904, as interface speeds and lane counts differ.
