TMDS141RHAR

Specialized Overview

The TMDS141RHAR is an HDMI Hider integrated circuit manufactured by Texas Instruments, designed to extend HDMI signal transmission over a 1-meter cable. It accommodates signal distortion caused by internal cable capacitance between the connector and receiver. The device contains four TMDS repeaters supporting signaling rates up to 2.25 Gbps and an I2C repeater for extended display data channel linking. It operates within a supply voltage range of 3V to 3.6V and functions at temperatures from 0°C to +70°C. The component is housed in a 40-VQFN package with an exposed pad.

Specialized Feature Summary

• Integrates four TMDS repeaters to transmit digital content at high signaling rates
• Includes an I2C repeater to link extended display identification data channels
• Designed specifically to compensate for signal distortion in 1-meter HDMI cables

Specialized Applications

• DisplayPort to TMDS translator interface systems
• HDMI extension applications requiring 1-meter cable accommodation
• Digital display interfaces needing signal integrity restoration

Specialized Procurement Notes

Verify the specific ordering suffix RHAR corresponds to the required tape and reel packaging configuration. Confirm that the VQFN-40 package dimensions match the PCB footprint requirements. Ensure the operating temperature range of 0°C to +70°C aligns with the target environment specifications before finalizing procurement decisions.

Specialized Selection Notes

Select this component when signal degradation over a fixed 1-meter HDMI cable length is observed. It is suitable for designs requiring both TMDS data repetition and I2C bus extension. Consider the 3V to 3.6V supply requirement and thermal characteristics of the exposed pad VQFN package during layout planning.

Specialized Part Context

This part belongs to the TMDS141 series of display interface ICs. It serves as a specialized solution for maintaining signal integrity in HDMI connections where passive cabling causes unacceptable attenuation or distortion. The device bridges the gap between source transmitters and receivers in compact display architectures.
