PI3HDMI412-AZHE

Specialized Overview

The PI3HDMI412-AZHE is a bidirectional, passive signal switch designed for high-resolution video networks based on DVI/HDMI standards and TMDS signaling. It functions as a 4-differential channel, 2:1 multiplexer/demultiplexer with a maximum data rate of 4.0 Gbps. The device provides near-zero propagation delay (250ps max) and low bit-to-bit skew to maintain signal integrity. It operates on a 3.3V supply voltage with a quiescent current of 200 µA. ESD protection is rated at 8kV HBM for data bits and 2kV HBM for select bits. The component supports hot insertion and features switching speeds of 4ns.

Specialized Feature Summary

• Bidirectional passive switching capability suitable for both driver and receiver sides
• Low attenuation and minimal signal degradation for high-speed differential signals
• Integrated ESD protection compliant with consumer electronics requirements

Specialized Applications

• PC graphics applications connecting multiple display units such as LCD monitors, projectors, and TVs
• Consumer video applications switching between source components like DVD players, STBs, and D-VHS devices
• High-resolution video networks requiring DVI/HDMI compliance

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and environmental rating. Confirm that the ZH suffix corresponds to the 42-pin TQFN package variant. Ensure compatibility with system power supply voltages and logic levels before integration.

Specialized Selection Notes

Select this component for designs requiring a passive, bidirectional switch for TMDS signals without active re-driving. Consider the 42-pin TQFN or 48-pin BQSOP packages based on board space constraints. Verify that the 4.0 Gbps data rate meets the bandwidth requirements of the target HDMI/DVI resolution.
