PI3HDMI412FTBE

Specialized Overview

The PI3HDMI412FT is a passive bidirectional 4-differential channel, 2:1 Mux/DeMux switch designed for DVI and HDMI signal processing. It supports data rates up to 1.65Gbps with a -3dB bandwidth of 1.5GHz. The device features near-zero propagation delay (max 200ps) and low bit-to-bit skew. Electrical characteristics include crosstalk of -35dB at 1.65Gbps and isolation of -37dB at 1.65Gbps. ESD protection provides 8kV HBM on data bits and 2kV HBM on select bits. It operates on a single 3.3V power supply within the -40°C to +85°C temperature range.

Specialized Feature Summary

• Bidirectional switching capability allows placement at either driver or receiver sides in video networks.
• Flow-through pinout design facilitates easy integration into existing PCB layouts without complex routing.
• Hot insertion capable operation ensures safe connection and disconnection of video sources during system runtime.

Specialized Applications

• PC graphics applications connecting multiple display units such as LCD monitors, projectors, and TVs.
• Consumer video systems switching between source components like DVD players, D-VHS, and set-top boxes.
• High-resolution video networks requiring TMDS signal processing compliant with DVI/HDMI standards.

Specialized Procurement Notes

Verify package type availability, as the component is offered in both 42-pin TQFN and 48-pin BQSOP configurations. Confirm ordering suffixes for tape and reel options if required for automated assembly processes. Ensure compatibility with standard 3.3V logic levels for the SEL control pin interface.

Specialized Selection Notes

Select this component for designs requiring passive switching of high-speed differential signals without active equalization. Verify that the 1.65Gbps maximum data rate meets the resolution requirements of the target application. Consider the specific package dimensions of the TQFN or BQSOP variants based on available board space constraints.

Specialized Part Context

This component belongs to the PI3HDMI series of switch circuits targeted at high-resolution video networks. It is manufactured by Pericom Semiconductor Corporation, which was later acquired by Diodes Incorporated. The device serves as a foundational building block for managing multiple video inputs or outputs in consumer electronics and PC peripherals.

Specialized Replacement Considerations

Check for updated part numbers from Diodes Incorporated following the acquisition of Pericom. Verify pinout compatibility if substituting with other 2:1 mux/demux switches in the same family. Ensure replacement parts maintain the same bidirectional and hot-swap capabilities.
