PI3EQX16908GLZLEX

Analog Switches - Special Purpose Overview

The PI3EQX16908GLZLEX is an eight-channel ReDriver designed for high-speed serial links up to 16 Gbps. It supports PCIe Gen 4 and UPI protocols, featuring programmable linear equalization, output swing, and flat gain via I2C control. The device utilizes eight 100-Ohm differential CML data inputs and outputs to extend signals across distant pathways. It operates on a single 3.3V ±0.3V supply within an industrial temperature range of -40°C to 85°C. The component is housed in a 72-contact W-QFN50110 package.

Analog Switches - Special Purpose Feature Summary

• Supports multi-data rate serial links from 2.5 to 16 Gbps with integrated linear equalization.
• Provides independent channel configuration for receiver equalization, output swing, and flat gain.
• Transparent to link training, idle states, and out-of-band signaling.
• Features I2C selectable programming with a 1-bit address selection option.

Analog Switches - Special Purpose Applications

• Networking infrastructure
• Enterprise systems
• Server platforms
• Storage solutions

Analog Switches - Special Purpose Procurement Notes

Verify the complete part number including the ZL suffix to ensure the correct 72-contact TQFN package and tape-and-reel packaging configuration. Confirm RoHS 3 compliance and lead-free status requirements against specific project standards. Check for automotive qualification needs, as standard versions differ from AEC-Q100 qualified parts requiring separate contact.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring PCIe Gen 4 or UPI signal integrity extension over long traces. Ensure the design accommodates the 3.3V power supply and I2C interface for dynamic equalization tuning. Verify that the PCB layout supports the W-QFN50110 footprint and thermal requirements for the industrial temperature range.

Analog Switches - Special Purpose Part Context

This device belongs to Diodes Incorporated's ReDriver family, which focuses on signal conditioning for high-speed interfaces. The PI3EQX16908GL specifically targets the 16 Gbps bandwidth requirement, distinguishing it from lower-speed variants like the 8 Gbps models. It serves as a critical component for maintaining signal quality in complex digital interconnects.

Analog Switches - Special Purpose Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in the provided documentation. Engineers should evaluate other 8-channel ReDrivers from the same manufacturer series, ensuring compatibility with 16 Gbps speeds, CML I/O levels, and the 72-contact TQFN package form factor.
