PI3HDMI511ZLE+DAX

Specialized Overview

The PI3HDMI511ZLE+DAX is an HDMI 1.4 compliant TMDS Redriver designed for source-side applications, manufactured by Diodes Incorporated in a 32-contact TQFN package. It supports data rates up to 3.4 Gbps per lane and accommodates video formats including 4K x 2K at 24Hz, 3D Video, and Deep Color up to 48-bit per pixel. The device operates on a single 3.3V power supply with a recommended operating voltage range of 3.0V to 3.6V. Key electrical parameters include a typical supply current of 150 mA, propagation delay of 2000 ps, and peak-to-peak output jitter of 30 ps for the clock channel. It features integrated ESD protection rated at 8kV contact and 8kV HBM.

Specialized Feature Summary

• Supports HDMI 1.4 specifications with programmable equalization, emphasis, and amplitude settings to optimize signal integrity.
• Converts low-swing DC or AC coupled differential inputs into open-drain current steering outputs terminated differentially.
• Includes built-in Rx sense detection and idle clock detection functions to manage power states and output squelch.
• Features an integrated passive DDC level shifter compatible with 3.3V sources and 5V sinks.

Specialized Applications

• Notebook computers
• Docking stations
• Set-Top Boxes (STB)
• A/V Home entertainment systems
• Dongles and switch boxes

Specialized Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the specific tape and reel packaging requirements for your assembly line. Ensure compliance with RoHS standards and lead-free green material specifications as documented in the datasheet before finalizing procurement orders.

Specialized Selection Notes

Select this component for source-side HDMI applications requiring signal re-driving up to 3.4 Gbps. Consider its integrated DDC level shifting and ESD protection capabilities when designing interfaces for consumer electronics. Evaluate the thermal characteristics and decoupling capacitor placement guidelines provided in the datasheet to ensure stable operation within the specified temperature range.

Specialized Part Context

This part belongs to the PI3HDMI511 family of HDMI Redrivers from Diodes Incorporated. It is specifically engineered for source-side applications, distinguishing it from sink-side variants like the PI3HDMI611. The ZLE+DAX designation indicates a Pb-free, Green product packaged in a 32-contact TQFN format, supplied in a tape and reel configuration for automated assembly processes.

Specialized Replacement Considerations

The PI3HDMI611 serves as a related alternative but is designed for sink-side applications rather than source-side use. Designers should verify pin compatibility and functional differences between source and sink variants when considering substitutes.

Specialized FAQ

How does the PI3HDMI511 handle power consumption when no valid signal is present?

The device utilizes intelligent power management techniques to automatically enter low power states, such as power-down mode, when no valid signal is detected on the TMDS link or when the input clock frequency is below 10MHz.

What is the function of the Rx sense detection feature?

The Rx sense detector checks for the presence of a 50 ohm termination resistor within the HDMI receiver chipset. If not detected, the IC turns off its input termination resistors and enters power-down mode to conserve energy.

Can the PI3HDMI511 support Dual Mode DisplayPort devices?

Yes, the device supports Dual Mode DisplayPort source devices by converting their signals into HDMI compliant outputs with proper signal swing.
