PI3WVR31310AZLEX

Overview

The PI3WVR31310AZLEX is a high-speed passive switch IC manufactured by Diodes Incorporated, housed in a 60-pin TQFN (5x9mm) package. It functions as a 3:1 multiplexer or 1:3 demultiplexer for DisplayPort and HDMI signals. The device supports DP 1.2 at 5.4 Gb/s and HDMI 2.0 at 6 Gb/s across four differential pairs per port. It operates on a single 3.3V supply with a voltage range of 3.0V to 3.6V. Key electrical parameters include a maximum on-resistance of 12 Ohms for high-speed channels and a -3dB bandwidth of 5.4 GHz. The component includes integrated DDC/AUX and HPD signal switching capabilities.

Feature Summary

• Configurable 3:1 Mux or 1:3 Demux architecture supporting both DisplayPort and HDMI standards
• Automatic port priority selection based on Hot Plug Detect (HPD) status in demux mode
• Integrated switching for auxiliary, DDC, and cable detect signals alongside main video paths
• Low power consumption with ESD protection rated at 2kV HBM on all I/O pins

Applications

• Notebook computers requiring display output switching
• Monitor and TV sink applications
• Video switch boxes and matrix switchers
• Embedded systems utilizing DP/HDMI interfaces

Procurement Notes

Verify the specific ordering suffix 'ZLEX' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the RoHS3 compliance status meets current environmental regulations for the target market. Ensure the 60-pin TQFN footprint matches the PCB layout design specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring simultaneous switching of high-speed differential video signals and control lines like DDC and AUX. It is suitable for applications needing manual or automatic port selection via HPD detection. Ensure the system operates within the specified 3.0V to 3.6V supply range and accommodates the thermal characteristics of the exposed pad ground connection.

Part Context

This part belongs to the PI3WVR31310A family of high-speed video switches from Diodes Incorporated. The base model PI3WVR31310A represents the standard die configuration, while the AZLEX suffix indicates the specific lead-free, green material composition and tape-and-reel packaging variant intended for surface-mount technology production lines.

Replacement Considerations

Direct pin-to-pin replacements are limited within the same product family. Verify compatibility with alternative models such as the PI3WVR41310 for higher bandwidth requirements or different channel counts. Cross-reference datasheets to ensure interface protocols and voltage levels align with existing system designs.

FAQ

Does the PI3WVR31310AZLEX support HDMI source applications?

No, the HDMI mode strictly supports HDMI-sink applications and does not support HDMI-source applications.

How is port selection managed in 1:3 Demux mode?

Port selection can be performed manually using SEL pins or automatically by detecting HPD presence from the output ports, with priority determined by the PRI_SEL pin.

What is the maximum data rate supported by this switch?

The device supports up to DP 1.2 at 5.4 Gb/s and HDMI 2.0 at 6 Gb/s.
