PI3HDX12221ZLDEX

Specialized Overview

The PI3HDX12221ZLDEX is a 2-to-1 active multiplexer switch for 4-channel HDMI links, supporting data rates up to 12Gbps for the HDMI 2.1 standard. It provides maximum equalizer gain controls of +11dB at 6GHz and +7dB at 3GHz to compensate for channel insertion loss. The device features a non-blocking linear ReDriver design that transparently transmits differential signals while linearly compensating for channel loss. It includes CTLE equalizers at the inputs to reduce ISI jitters and supports programmable flat gain and output linearity adjustments. The component operates on a single 3.3V power supply with a tolerance of +/-0.3V and functions within a commercial temperature range of 0°C to +70°C.

Specialized Feature Summary

• Integrates a 2-to-1 mux switch configuration for four-channel HDMI operation with support for HDMI 2.1, 2.0, and 1.4 signal speeds.
• Features a non-blocking linear ReDriver design that ensures transparent transmission of pre-shoot and de-emphasis waveforms from source to receiver.
• Utilizes quad-level pin strap control through combinational logic to select equalizer gain values, flat gains, and output swing linearity settings.

Specialized Applications

• Digital TVs
• Display monitors
• Gaming consoles
• Laptop and Desktop PCs
• Workstation and Server systems

Specialized Procurement Notes

Verify the specific ordering suffix ZLDEX corresponds to the 40-pin TQFN package in a tape and reel format. Confirm compliance with RoHS 2 and RoHS 3 directives, ensuring the device is lead-free and halogen/antimony free. Check for automotive qualification requirements if AEC-Q100 standards or PPAP capabilities are necessary for the target application.

Specialized Selection Notes

Select this component when designing systems requiring high-speed HDMI 2.1 signal switching with integrated signal integrity compensation. Ensure the design accommodates the 3.3V single power supply requirement and the 0°C to +70°C commercial operating temperature range. Consider the compact 3x6mm package dimensions for space-constrained layouts.

Specialized Part Context

The PI3HDX12221ZLDEX belongs to Diodes Incorporated's PI3HDX series of active mux switches and linear Redrivers. This series is designed to address signal integrity challenges in high-bandwidth video interfaces by combining switching functionality with channel loss compensation.

Specialized Replacement Considerations

Consult official documentation for qualified substitutes. Verify compatibility with HDMI 2.1 specifications and ensure equivalent package dimensions and pin configurations before replacement.
