TMDS1204RNQT

Specialized Overview

The TMDS1204RNQT is a hybrid redriver supporting HDMI 2.1 data rates up to 12Gbps, compatible with HDMI 1.4b and 2.0b. It supports 3 and 4 lane Fixed Rate Link (FRL) at 3, 6, 8, 10, and 12Gbps. The device operates on a single 3.3V supply (VCC) and accepts VIO levels of 1.2V, 1.8V, or 3.3V. It features AC-coupled or DC-coupled inputs/outputs, adaptive/fixed equalization up to 12dB at 6GHz, and an integrated HPD level shifter. Power consumption ranges from 575mW (limited mode, 12G FRL) to 220mW (linear mode, 12G FRL), with 0.6mW in power-down. It is housed in a 40-pin WQFN package.

Specialized Feature Summary

• Hybrid redriver architecture supporting both linear and limited modes for source and sink applications
• Integrated Hot Plug Detect (HPD) level shifter converting 5V signals to 1.8V or 3.3V LVCMOS
• Supports full lane swap on main lanes and integrated fan-out buffer for separate clock/data paths
• Configurable via I2C or pin-strap with digital display control (DDC) snooping function

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 RNQT corresponds to the WQFN-40 package and reel packaging configuration. Confirm the temperature grade matches the commercial specification (TMDS1204) rather than the industrial variant (TMDS1204I). Ensure the component version aligns with the latest datasheet revision SLLSF57A revised April 2024 for accurate electrical characteristics.

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 limited redriver mode for source applications to ensure compliant output levels independent of GPU voltage. Select the linear redriver mode for sink applications to maintain transparency during link training. Verify compatibility with AC or DC coupling requirements based on the upstream transmitter design.

Specialized Part Context

The TMDS1204 belongs to Texas Instruments' family of display interface ICs designed for high-speed multimedia transmission. It serves as a bridge between DP++ sources and HDMI sinks or as a direct HDMI redriver. The device integrates signal conditioning and protocol translation capabilities within a compact footprint suitable for space-constrained consumer electronics and professional AV equipment.
