PI3WVR31212AZLEX

Overview

The PI3WVR31212AZLEX is a DP/HDMI 1:2 demultiplexer switch manufactured by Diodes Incorporated. It features one passive output port supporting DisplayPort 1.2 at 5.4Gbps and one active output port with an integrated DP to HDMI re-driver supporting HDMI 1.4 at 3.4Gbps. The device operates on a single 3.3V supply (3.0V to 3.6V) within a -40°C to +85°C temperature range. It utilizes a 60-pin TQFN package (5x9mm). Key electrical parameters include a maximum passive switch resistance of 50 ohms, 2KV HBM ESD protection, and a typical quiescent current of 5mA when Port 2 is active without TMDS input.

Feature Summary

• Integrated DP to HDMI level shifter for active port operation
• Supports auto port priority selection based on HPD status
• Configurable equalization and pre-emphasis settings via I2C or pin control
• Supports Type 1 and Type 2 cable ID registers

Applications

• Notebook computers
• Video dongles

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The 'ZLE' suffix indicates a tape and reel configuration, while other suffixes may denote different packaging formats. Ensure compatibility with RoHS requirements as specified in the manufacturer's datasheet before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a dual-mode video switch with integrated signal conditioning. The choice between pin control and I2C modes depends on system complexity and available GPIO resources. Consider the power consumption differences between passive and active port operations when designing the thermal management strategy.

FAQ

How does the device handle port selection?

The device supports auto port priority selection based on Hot Plug Detect (HPD) signals. Users can configure priority using the PRI_SEL pin in pin control mode or via I2C registers.

What is the maximum data rate supported by the passive port?

The passive output port supports DisplayPort 1.2 at a maximum data rate of 5.4Gbps.

Can the active port operate independently of the passive port?

Yes, when Port 2 (active) is selected, the internal DP to HDMI level shifter is enabled, and Port 1 (passive) is shut down.
