TMDS171IRGZT

Specialized Overview

The TMDS171IRGZT is a display interface integrated circuit manufactured by Texas Instruments, functioning as a TMDS retimer compliant with HDMI 1.4b specifications. It supports data rates up to 3.4 Gbps and utilizes an I2C interface for configuration. The device operates within a supply voltage range of 3.135V to 3.465V and draws a typical operating current of 350 mA. It is housed in a 48-VQFN package with dimensions of 7x7 mm and includes an exposed pad. The component is rated for industrial temperatures, operating between -40°C and +85°C.

Specialized Feature Summary

• Retimes TMDS signals to restore signal integrity for high-speed display interfaces
• Supports HDMI 1.4b standard compliance through dedicated TMDS channel processing
• Configurable via I2C interface for system integration flexibility

Specialized Applications

• HDMI source devices requiring signal reconditioning
• Display receivers needing TMDS signal restoration
• Consumer electronics utilizing HDMI 1.4b connections

Specialized Procurement Notes

Verify the specific suffix 'RGZT' against the manufacturer's official datasheet to confirm the package type, temperature grade, and reel quantity. Ensure the ordering part number matches the exact electrical and mechanical specifications required for the design. Cross-reference the RoHS status and humidity sensitivity classification before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing systems that require HDMI 1.4b TMDS retiming capabilities. Confirm that the 48-VQFN package footprint fits the PCB layout constraints. Verify that the 3.135V to 3.465V supply voltage range aligns with the system power rails. Ensure the I2C interface is available for necessary configuration settings during operation.

Specialized Part Context

This part belongs to the TMDS retimer family from Texas Instruments, designed specifically for display interface applications. It addresses signal degradation issues in high-speed digital video transmission lines. The device complements other interface solutions by providing active signal regeneration rather than passive buffering.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements within the same TMDS retimer series. Verify compatibility with existing I2C configuration registers if substituting with similar models. Ensure the replacement maintains the 3.4 Gbps data rate support and HDMI 1.4b compliance.
