PI3EQX32904ZREX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX32904ZREX is a low-power, high-performance 32Gbps four-channel ReDriver manufactured by Diodes Incorporated. It supports PCIe 5.0, SAS4, and CXL protocols with independent channel configuration for receiver equalization, output swing, and flat gain. The device features 100Ω differential CML I/Os, automatic receiver detect, and rate/coding agnostic operation transparent to link training. Powered by a single 3.3V supply, it operates within a temperature range of -40°C to +85°C. The component is housed in a 46-pin W-QFN3063-46 package (Code ZR) and is supplied in tape and reel format.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable linear equalization, output swing, and flat gain via I2C control to optimize signal integrity across various physical mediums.
• Supports PCIe 5.0, SAS4, and CXL protocols with four fully independent differential channels that are rate and coding agnostic.
• Integrates adaptive power management and automatic receiver detect functions to maximize battery life and manage signal activity.

Signal Buffers, Repeaters, Splitters Applications

• Extending signals between Protocol ASICs and switch fabrics over cables or distant data pathways.
• Optimizing signal integrity in systems requiring high-speed serial link transmission up to 32Gbps.
• Applications demanding transparent link training and independent channel configuration for complex interface architectures.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'ZR' corresponds to the 46-pin W-QFN3063-46 package and tape/reel packaging configuration. Confirm compliance requirements such as RoHS 3 and halogen-free status against current project specifications. Ensure the 3.3V supply voltage and -40°C to +85°C operating temperature range align with the target system environment before procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing interfaces for PCIe 5.0, SAS4, or CXL protocols requiring 32Gbps data rates. It is suitable for applications needing independent channel control for equalization and swing adjustment. Consider the W-QFN3063-46 package size and thermal characteristics for PCB layout. Verify that the I2C control interface fits the system's management architecture.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3EQX32904 product line from Diodes Incorporated, designed as a high-performance ReDriver. It is distinct from other variants in the series by its specific 32Gbps capability and four-channel configuration. The ZREX suffix indicates the Pb-free, green, tape-and-reel packaging variant of the base PI3EQX32904 device.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes within the same family include the PI3EQX32904ZRIEX if a different package code is acceptable. Verify pin compatibility and electrical parameters before replacing. Contact Diodes Incorporated for automotive-qualified alternatives if AEC-Q100 compliance is required.
