PI3HDX12221BZLDEX

Analog Switches - Special Purpose Overview

The PI3HDX12221BZLDEX is a 2-to-1 active multiplexer switch for 4-channel HDMI links, supporting data rates up to 12Gbps compliant with the HDMI 2.1 standard. It integrates a non-blocking linear ReDriver design to transparently transmit differential signals while compensating for channel insertion loss. The device provides maximum equalizer gain controls of +8.8dB at 6GHz (HDMI 2.1) and +5.5dB at 3GHz (HDMI 2.0). It operates on a single 3.3V power supply within an industrial temperature range of -40°C to +85°C. The component is housed in a 40-contact TQFN package measuring 3x6mm.

Analog Switches - Special Purpose Feature Summary

• Integrates a 2-to-1 Mux switch configuration for 4-channel HDMI operation with linear ReDriver capabilities.
• Supports HDMI 1.4/2.0/2.1 standards and DisplayPort Dual-Mode V1.1 applications.
• Features quad-level pin strap or I2C control for flexible equalizer gain, flat gain, and output swing linearity selection.
• Includes CTLE equalizers at inputs to reduce ISI jitters and extend channel length.

Analog Switches - Special Purpose Applications

• Digital TVs
• Display Monitors
• Gaming Consoles
• Workstation and Server Systems
• Docking, KVM and PC Peripherals

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ZLDEX corresponds to the 40-pin TQFN 3x6mm package and tape/reel packaging format. Confirm that the E suffix indicates lead-free and green compliance status as defined by the manufacturer's environmental definitions. Ensure the industrial temperature grade (-40°C to +85°C) matches the system requirements before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring high-speed HDMI 2.1 signal switching with integrated signal integrity compensation. The choice is appropriate for applications needing transparent transmission of pre-shoot and de-emphasis waveforms. Consider the compact 3x6mm footprint if space constraints are critical. Verify compatibility with existing I2C or pin-strapping control architectures for gain adjustment.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3HDX12221B product line from Diodes Incorporated, designed specifically for high-bandwidth video interfaces. It serves as a solution for extending HDMI link distances and managing signal quality in multi-source display environments. The device complements other ReDriver and mux solutions by combining switching functionality with active signal conditioning in a single package.

Analog Switches - Special Purpose Replacement Considerations

Check for direct substitutes within the PI3HDX series that offer similar 4-channel HDMI 2.1 support. Verify pinout compatibility and electrical specifications against alternative active mux switches. Ensure any replacement maintains the required 12Gbps data rate capability and linear ReDriver performance characteristics.
