PI3DPX8121AZLEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX8121AZLEX is a 2-to-1 active multiplexer switch designed for 4-lane DisplayPort links, supporting data rates up to 13.5Gbps per lane. It covers eDP 1.5, DP 1.4, and DP 2.1 standards including UHBR13.5. The device integrates a Link Training Tunable Linear ReDriver (LT-Tunable) with CTLE equalizers to compensate channel loss and reduce ISI jitters. Maximum equalizer gain reaches +10.2dB at 6.75GHz. It operates on a single 3.3V supply within an industrial temperature range of -40°C to +85°C. The component is housed in a 60-pin, 5x9mm TQFN package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports 2:1 active mux configuration for 4-lane DisplayPort operation with LTTPR ReDriver data path compatibility
• Features quad-level pin strap control via combinational logic for flexible selection of equalizer gain, flat gain, and output swing linearity
• Integrates programmable flat gain and linear adjustments to optimize eye diagram opening and support system transmitter/receiver link training

Signal Buffers, Repeaters, Splitters Applications

• Laptop and Desktop PCs
• Workstation and Server Systems
• Docking, KVM and PC Peripherals
• Display Monitors

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZLEX corresponds to the 60-pin 5x9mm TQFN package with tape and reel packaging. Confirm RoHS compliance and green status requirements against current environmental directives. Ensure the selected variant matches the required industrial temperature rating and single 3.3V power supply specifications for the target application design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal switching between two DisplayPort sources to a single sink while maintaining high-speed integrity up to 13.5Gbps. The integrated linear redriver functionality makes it suitable for applications needing channel loss compensation without external equalization components. Verify that the pin-strapped configuration options align with the board layout constraints for gain and linearity settings.
