PI3PCIE3442AZLEX-55

Specialized Overview

The PI3PCIE3442AZLEX-55 is a differential exchange switch manufactured by Diodes Incorporated. It supports two full PCI Express lanes operating at 8.0 Gbps PCIe 3.0 performance. The device features bi-directional operation with low bit-to-bit skew of 10ps and low crosstalk of -29dB at 2.5GHz. Operating voltage ranges from 3.0V to 3.6V, and it functions within an industrial temperature range of -40°C to 85°C. It utilizes a 40-contact TQFN package (ZL) measuring 3x6mm.

Specialized Feature Summary

• Supports 8-channel differential pass-through switching between four ports
• Features low insertion loss and minimal signal degradation
• Includes ESD tolerance of 2kV HBM for enhanced protection

Specialized Applications

• Switching DisplayPort 1.2 signals in PC or notebook systems
• Connecting tablet devices to external display monitors
• Routing high-speed differential signals in portable electronics

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm RoHS compliance status and lead-free requirements prior to procurement. Ensure the component meets environmental standards for halogen and antimony content as defined by the manufacturer's green product guidelines.

Specialized Selection Notes

Select this component when designing circuits requiring bidirectional PCIe lane switching with minimal signal distortion. Verify that the system operates within the specified 3.3V ±10% power supply range. Ensure the PCB layout accommodates the 40-contact TQFN footprint dimensions of 3x6mm for proper thermal and mechanical integration.

Specialized Part Context

This part belongs to the PI3PCIE3442A series of differential exchange switches. It is designed specifically for high-speed interface applications requiring reliable signal routing. The device integrates control logic for seamless port selection without external buffering components.

Specialized Replacement Considerations

PI3PCIE3442AZHEX: Offers identical electrical functionality but utilizes a 42-contact TQFN package instead of the 40-contact variant.
