TMDS171RGZT

Specialized Overview

The TMDS171RGZT is a display interface integrated circuit manufactured by Texas Instruments, functioning as a TMDS retimer. It supports data rates up to 3.4 Gbps for HDMI 1.4b and digital video interfaces. The device operates within a supply voltage range of 3.135 V to 3.465 V and draws a typical operating current of 350 mA. It utilizes an I2C interface for configuration and control. The component is housed in a 48-VQFN package with dimensions of 7x7 mm, designed for surface mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C.

Specialized Feature Summary

• Retimes TMDS signals to restore signal integrity for high-speed digital video transmission
• Supports HDMI 1.4b specifications and standard digital video interfaces
• Configurable via I2C serial interface for system integration

Specialized Applications

• HDMI source devices requiring signal regeneration
• Digital display interface systems
• Video distribution equipment

Specialized Procurement Notes

Verify the specific suffix RGZT to confirm the tape-and-reel packaging format and commercial grade temperature rating. Ensure compatibility with the 3.3V nominal supply domain. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the datasheet revision date to ensure alignment with current design specifications.

Specialized Selection Notes

Select this component when a 3.4 Gbps TMDS retimer is required for HDMI 1.4b compliance. Compare against the TMDS181 if higher 6 Gbps bandwidth is needed. Verify that the 48-pin VQFN footprint fits the PCB layout constraints. Ensure the I2C address configuration meets the system bus requirements.

Specialized Part Context

This part belongs to the TMDS171 series of retimers from Texas Instruments. It is distinct from the TMDS181, which offers higher speed capabilities. The RGZT suffix indicates a specific packaging variant within the broader TMDS171 family, differentiated from the RGZR reel option.

Specialized Replacement Considerations

The TMDS171IRGZT serves as the industrial temperature grade equivalent. For higher bandwidth applications, the TMDS181RGZT is a compatible upgrade path. Direct pin-to-pin replacements from other manufacturers are not explicitly confirmed in public documentation.
