TMDS181RGZT

Specialized Overview

The TMDS181RGZT is a display interface integrated circuit manufactured by Texas Instruments, housed in a VQFN-48 package. It functions as a TMDS retimer supporting data rates up to 6 Gb/s for digital video and HDMI applications. The device operates on supply voltages of 1.2 V and 3.3 V, with a maximum operating frequency of 400 kHz for control interfaces. It supports I2C communication for configuration and monitoring. The component is rated for an operating temperature range from -40°C to +85°C and draws approximately 350 mA during operation.

Specialized Feature Summary

• Supports high-speed TMDS signal retiming for HDMI 2.0 compliance
• Configurable via I2C interface for flexible system integration
• Automatically switches between retimer and redriver modes based on clock frequency

Specialized Applications

• HDMI 2.0 video transmission systems
• Digital display interface signal conditioning
• High-definition multimedia retiming circuits

Specialized Procurement Notes

Verify the specific suffix RGZT against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C bus voltage levels and check humidity sensitivity handling requirements during storage and assembly. Confirm that the 6 Gbps data rate aligns with the target HDMI version requirements.

Specialized Selection Notes

Select this component when HDMI 2.0 signal integrity requires active retiming rather than passive equalization. Consider the VQFN-48 footprint for PCB layout constraints. Verify that the 350 mA current draw fits within the system power budget. Ensure the design supports the necessary I2C addressing scheme for register configuration.

Specialized Part Context

This part belongs to the TMDS181 series of display interface ICs designed for high-bandwidth video applications. It serves as a signal regeneration solution for long cable runs or complex board traces. The device complements other interface solutions like the TMDS171, offering higher data rate capabilities for modern display standards.

Specialized Replacement Considerations

The TMDS171 is pin-to-pin compatible but supports only 3.4 Gbps data rates. Use TMDS171 only if the application strictly adheres to HDMI 1.4b electrical parameters and does not require 6 Gbps throughput.
