TMDS171IRGZR

Specialized Overview

The TMDS171IRGZR is a display interface integrated circuit manufactured by Texas Instruments, functioning as a 3.4-Gbps HDMI 1.4b TMDS retimer. It operates within a supply voltage range of 3.135V to 3.465V and utilizes an I2C interface for configuration. The device is housed in a 48-VQFN package with dimensions of 7x7 mm and includes a bare pad for thermal management. Designed for surface mount installation, it supports industrial temperature ranges from -40°C to +85°C. The component is supplied in reel packaging with a factory quantity of 2,500 units.

Specialized Feature Summary

• Provides signal regeneration for high-speed TMDS data streams to maintain integrity over long traces or lossy channels.
• Supports HDMI 1.4b specifications including Deep Color and x.v.Color formats through adaptive equalization.
• Integrates on-chip configuration registers accessible via the I2C serial interface for flexible system integration.

Specialized Applications

• High-definition video transmission systems requiring signal restoration
• HDMI source and sink devices operating at 1080p and 4K resolutions
• Professional audiovisual equipment utilizing DisplayPort-to-HDMI conversion

Specialized Procurement Notes

Verify the specific suffix IRGZR against official Texas Instruments documentation to confirm the reel packaging format and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet before procurement.

Specialized Selection Notes

Select this component when designing systems requiring compliance with HDMI 1.4b standards and operation at data rates up to 3.4 Gbps. Consider the 48-VQFN package constraints and thermal dissipation requirements associated with the bare pad design during PCB layout.

Specialized Part Context

This part belongs to the TMDS171 series of retimers designed specifically for HDMI applications. It serves as a critical link in maintaining signal quality between video sources and displays, distinguishing itself from drivers or receivers by its ability to regenerate clock and data signals.

Specialized Replacement Considerations

The TMDS181IRGZT is a documented alternative offering higher speed capabilities at 6 Gbps. Verify pinout compatibility and software configuration differences before substituting, as the TMDS181 targets HDMI 2.0 specifications.
