PI3HDMI511AZLE

Specialized Overview

The PI3HDMI511AZLE is a video interface integrated circuit manufactured by Diodes Incorporated, designed as an HDMI 1.4 compliant redriver for source-side applications. It operates in a TQFN-32 surface-mount package to facilitate signal integrity over extended traces. The device supports high-bandwidth digital video formats including 4K x 2K resolution at 24Hz and standard 1080p/720p configurations. Key electrical characteristics include support for pixel clocks up to 340MHz and data rates of 3.4Gbps per channel. It features programmable equalization, pre-emphasis, and amplitude settings to optimize signal quality. The component integrates passive DDC level shifting and includes ESD protection rated at 8kV HBM on I/O pins.

Specialized Feature Summary

• HDMI 1.4 compliant redriver with programmable equalization and pre-emphasis capabilities
• Integrated passive DDC level shifter and idle clock detection for automatic standby management
• Supports AC-coupled differential input interfaces and open-drain current steering outputs
• Includes output mute functionality and low-power shutdown modes

Specialized Applications

• Laptop computers requiring HDMI signal extension
• Set-top boxes (STB) and A/V home entertainment systems
• HDMI adapters and switch boxes
• HDMI extender cables and dongles

Specialized Procurement Notes

Verify the specific suffix 'ZLEX' against the requested model, as datasheets often list variants like PI3HDMI511ZLEX or PI3HDMI511ZLE. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the TQFN-32 package matches your PCB footprint requirements before finalizing orders.

Specialized Selection Notes

Select this component when designing source-side HDMI interfaces that require signal regeneration over long PCB traces or cables. It is suitable for applications needing 4K@24Hz support or standard 1080p/720p video transmission. Consider the TQFN-32 package size and thermal dissipation characteristics during layout. Verify compatibility with 3.3V power supplies if used in 5V tolerant systems.

Specialized Part Context

This part belongs to the Pericom HDMI redriver family, now under Diodes Incorporated. It complements other models like the PI3HDX511 series for DisplayPort applications. The device addresses signal integrity challenges in high-speed digital video interfaces by providing active equalization and buffering capabilities essential for maintaining data fidelity in consumer electronics.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements within the PI3HDMI511 series, such as PI3HDMI511ZLE or PI3HDMI511ZLEX. Verify functional equivalence regarding HDMI version support and package dimensions. Cross-reference with Diodes Incorporated documentation for any updated revisions or recommended alternatives.
