PI3EQX32908ZRIEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX32908ZRIEX is an eight-channel linear ReDriver manufactured by Diodes Incorporated, designed for high-speed serial data transmission. It supports PCIe 5.0, SAS4, and CXL protocols with a maximum data rate of 32 Gbps per channel. The device operates on a single 3.3 V power supply within an industrial temperature range of -40°C to +85°C. It utilizes a W-QFN-62 package (WQFN3590-62) and accepts CML input/output signals. Key electrical specifications include a minimum operating voltage of 3 V and a maximum of 3.6 V. The component integrates programmable linear equalization, output swing control, and flat gain adjustment to optimize signal integrity across various physical media.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports PCIe 5.0, SAS4, and CXL protocols with high linearity and ultra-low jitter characteristics.
• Features modern standby mode that reduces power consumption to below 5 mW during deep system sleep states.
• Offers programmable linear equalization, output swing, and flat gain via pin strapping or I2C control to extend PCB trace lengths.
• Includes automatic receiver detection and low-power modes for adaptive power management when signals are inactive.

• Server systems
• Storage arrays
• Network infrastructure equipment

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix ZRIEX against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and reel diameter specifications. Ensure the ordering part number matches the exact package variant required for the target PCB footprint. Cross-reference the RoHS compliance status and any recent production change notices (PCN) issued by Diodes Incorporated prior to finalizing procurement orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for designs requiring eight channels of linear equalization at speeds up to 32 Gbps. It is suitable for applications needing support for PCIe 5.0, SAS4, or CXL standards. Consider the W-QFN-62 package dimensions for layout constraints. Verify that the system power budget accommodates the active current draw while ensuring the I2C interface compatibility for dynamic configuration if pin strapping options are insufficient.
