PI3HDMI101-BZHE

Specialized Overview

The PI3HDMI101-BZHE is a 1:1 active HDMI ReDriver manufactured by Diodes Incorporated, designed for high-resolution video networks based on DVI/HDMI standards. It supports TMDS signal processing with a maximum signaling rate of 2.5 Gbps per channel and provides 36-bit DeepColor support compliant with HDMI revision 1.3. The device features integrated 50-ohm termination resistors at each high-speed input and an optimized equalization circuit to eliminate deterministic jitter from long cables. It operates on a single 3.3V ±5% supply voltage within a 42-contact TQFN package.

Specialized Feature Summary

• Integrated Rx termination detection circuitry that automatically disables internal 50-Ohm input termination when no external termination is detected in the downstream receiver chipset.
• Configurable output swing control offering five selectable levels (400mV to 1000mV) and configurable pre-emphasis/de-emphasis settings to optimize signal integrity across various cable lengths.
• Supports both AC-coupled and DC-coupled inputs while providing 8kV contact ESD protection on all input data and clock channels per IEC61000-4-2 standards.

Specialized Applications

• High-resolution video networks requiring extended cable lengths up to 25 meters
• Consumer video networks needing enhanced robust ESD/EOS protection
• DVI and HDMI signal processing systems supporting DeepColor

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging details. The 'E' suffix indicates Pb-free and Green material compliance. Confirm whether the 'X' suffix is required for tape and reel delivery formats. Ensure the component matches the ZH42 package code for mechanical compatibility during integration.

Specialized Selection Notes

Select this component for applications requiring a 1:1 active ReDriver solution for HDMI/DVI signals up to 2.5 Gbps. It is suitable for designs needing integrated input termination and automatic Rx termination detection to simplify PCB layout. Consider its 8kV ESD rating for consumer electronics exposed to handling risks.

Specialized Part Context

This part belongs to the PI3HDMI series of active ReDrivers developed by Pericom Semiconductor, now under Diodes Incorporated. It addresses signal degradation in high-bandwidth video interfaces by providing programmable equalization and output swing control. The device integrates sideband buffers alongside high-speed TMDS buffers for a complete interface solution.

Specialized Replacement Considerations

Check for PI3HDMI101-A as a potential predecessor variant. Verify pinout and electrical specifications against other 1:1 HDMI ReDrivers if sourcing alternatives. Ensure any substitute supports the same 3.3V supply and 42-pin TQFN package constraints.

Specialized FAQ

How does the PI3HDMI101-B handle input termination?
