TMDS1204RNQR

Specialized Overview

The TMDS1204RNQR is a hybrid redriver supporting HDMI 2.1 data rates up to 12Gbps, compatible with HDMI 1.4b and 2.0b. It features AC or DC-coupled inputs/outputs and supports 3 and 4-lane FRL at 3, 6, 8, 10, and 12Gbps. The device operates in linear mode for sink applications (transparent to link training) or limited mode for source applications (ensuring compliant levels). Key specifications include an adaptive/fixed equalizer up to 12dB at 6GHz, integrated HPD level shifting to 1.8V or 3.3V LVCMOS, and DDC snooping. Power consumption ranges from 0.6mW in power-down to 575mW active limited and 220mW active linear at 12Gbps FRL. It uses a single 3.3V supply and is housed in a 40-pin WQFN package.

Specialized Feature Summary

• Hybrid redriver architecture supporting both linear and limited modes for versatile sink and source applications
• Integrated HPD level shifter converting 5V signals to 1.8V or 3.3V LVCMOS levels
• Supports full lane swap on main lanes and includes an integrated fan-out buffer for separate clock/data paths
• Features DDC snooping capability for link configuration and signal detect output indicator

Specialized Applications

• Notebooks and desktops
• TVs and home theater systems
• Gaming systems
• Docking stations
• Pro audio, video, and signage

Specialized Procurement Notes

Verify the ordering suffix RNQR corresponds to the commercial temperature range (0°C to 70°C) and the specific 40-pin WQFN package dimensions. Confirm that the component matches the Texas Instruments datasheet SLLSF57A revision details. Ensure compatibility with the required I2C or pin-strap configuration settings before integration into the design.

Specialized Selection Notes

Select this component when designing HDMI 2.1 interfaces requiring support for Fixed Rate Link (FRL) modes up to 12Gbps. Choose the linear mode for sink-side channel shortening where transparency to link training is critical. Opt for the limited mode if acting as a source driver to ensure strict HDMI receptacle compliance. Verify thermal management requirements given the active power dissipation levels.

Specialized Part Context

The TMDS1204 is part of Texas Instruments' HDMI 2.1 interface portfolio, designed to extend signal integrity over PCB traces. It serves as a bridge between graphics processing units and display connectors, handling high-speed differential signaling. The device integrates essential control functions like HPD shifting and DDC monitoring, reducing the need for external discrete components in modern display architectures.
