PI3HDMI101ZHE

Specialized Overview

The PI3HDMI101ZHE is a 1:1 active HDMI ReDriver with an integrated I2C buffer, manufactured by Diodes Incorporated. It supports DVI and HDMI signals at data rates up to 2.5 Gbps per channel, enabling 36-bit Deep Color compliance. The device operates on a single 3.3V supply (3.135V to 3.465V) within a 0°C to 70°C temperature range. Key electrical parameters include 8kV contact ESD protection, propagation delay of ≤1ns, and integrated 50-Ohm input termination resistors. It features configurable output swing (400mV to 1000mV), pre-emphasis (0dB to 9.0dB), and de-emphasis settings via pin strapping.

Specialized Feature Summary

• Integrated optimized equalization circuitry that eliminates deterministic jitter caused by long cables without requiring complex configuration.
• Configurable output swing and pre-emphasis/de-emphasis levels to optimize signal integrity across various cable lengths.
• Built-in I2C buffer supporting 5V tolerance for robust sideband communication between source and sink devices.
• High-performance ESD/EOS protection rated at 8kV contact discharge on all high-speed data channels.

Specialized Applications

• High-resolution video networks based on DVI/HDMI standards
• Consumer electronics requiring extended cable lengths up to 25 meters
• PC graphics products and peripheral display interfaces

Specialized Procurement Notes

Verify the component status as discontinued or end-of-life through official manufacturer channels before design finalization. Confirm availability of recommended replacement parts such as the PI3HDX511FZLCEX if sourcing new inventory is required. Ensure RoHS3 compliance documentation is obtained from the supplier to meet environmental regulations.

Specialized Selection Notes

Select this component for applications requiring a single-channel active repeater with integrated sideband buffering. The fixed equalization setting simplifies design for standard cable runs, while pin-strapped controls allow customization for specific impedance or swing requirements. Ensure the PCB layout accommodates the 42-contact TQFN package with appropriate thermal management.

Specialized Part Context

This part belongs to the Pericom/PI3HDMI series of active redrivers designed for TMDS signal processing. It integrates both high-speed differential signaling buffers and low-speed I2C path buffers into a single solution, reducing board space compared to discrete implementations. The ZHE suffix indicates a lead-free, green 42-pin TQFN package.

Specialized Replacement Considerations

The PI3HDX511FZLCEX is listed as a manufacturer-recommended alternative. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.

Specialized FAQ

How is the equalization level configured?

Equalization is configured using two control pins, EQ_S0 and EQ_S1, which support four settings: 3dB, 8dB, 12dB, and 16dB, selected via internal pull-ups or external connections.

What is the maximum supported data rate?

The device supports a maximum signaling rate of 2.5 Gbps per channel, which corresponds to HDMI 1.3 bandwidth requirements.

Does the device require external termination resistors?

No, the PI3HDMI101 includes integrated 50-Ohm (±10%) termination resistors at each high-speed signal input, eliminating the need for external components.
