PI3WVR31313AZLEX

Overview

The PI3WVR31313A is a DP/HDMI 1:3 de-multiplexer switch manufactured by Diodes Incorporated. It features two passive output ports (Port 1 and Port 2) supporting DisplayPort 1.2 signals at data rates up to 5.4 Gbps, and one active output port (Port 3) with an integrated DP-to-HDMI re-driver supporting HDMI 1.4b signals at 3.4 Gbps. The device operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. It utilizes a 60-pin TQFN package measuring 5x9mm with a 0.4mm pitch. Control can be managed via pin control mode or I2C interface, enabling automatic port priority selection based on Hot Plug Detect (HPD) status.

Feature Summary

• Integrates two passive differential output channels for high-speed DisplayPort signals alongside one active channel featuring an internal level shifter for HDMI conversion.
• Supports flexible configuration through both hardware pin control and digital I2C interfaces, allowing dynamic adjustment of equalization and pre-emphasis settings.
• Provides intelligent auto-selection logic that prioritizes connected display ports based on HPD signals and configurable priority pins.
• Includes dedicated auxiliary, DDC, and cable detection signal routing capabilities across all three output ports.

Applications

• Notebook computers requiring multi-display connectivity
• Docking stations facilitating simultaneous video output
• Portable devices integrating DisplayPort and HDMI sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and tape-and-reel quantities. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.

Selection Notes

Select this component when a design requires splitting a single DisplayPort source into multiple destinations including both native DP displays and HDMI monitors. Ensure the PCB layout accommodates the 60-pin TQFN footprint and provides adequate thermal relief for the exposed pad.

Part Context

This device belongs to the PI3WVR series of video switches from Diodes Incorporated. It is designed to manage signal integrity and protocol translation between modern laptop graphics outputs and various external display standards.

Replacement Considerations

Check for updated revisions within the same product family. Verify pin compatibility if substituting with other PI3WVR models, as feature sets may vary regarding active versus passive port configurations.
