TDP1204RNQR

Overview

The TDP1204RNQR is a Texas Instruments HDMI 2.1 hybrid redriver supporting data rates up to 12 Gbps. It operates on a single 3.3-V supply and features AC-coupled or DC-coupled inputs and outputs. The device supports HDMI 2.1 fixed rate link (FRL) at 3, 6, 8, 10, and 12 Gbps for three and four lanes. It includes an integrated HPD level shifter for 5-V to 1.8-V/3.3-V conversion and a DDC buffer supporting levels down to 1.2 V. Power consumption in active limited mode at 12 Gbps is typically 575 mW, while linear mode consumes 220 mW. The component is housed in a 40-pin, 0.4 mm pitch, 4 mm × 6 mm WQFN package.

Feature Summary

• Hybrid redriver architecture supporting both source and sink applications via configurable linear or limited modes
• Integrated hot plug detect (HPD) level shifter with configurable push-pull or open-drain output options
• Programmable receiver equalizer providing up to 12 dB gain at 6 GHz
• Supports full lane swapping on main data lanes and digital display control (DDC) snooping

Applications

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

Procurement Notes

Verify the specific ordering suffix RNQR against the manufacturer's current orderable addendum to confirm availability and exact packaging configuration. Ensure that the commercial temperature range specification aligns with the target system environment requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing HDMI 2.1 interfaces requiring support for fixed rate links up to 12 Gbps. The choice between linear and limited redriver modes should be determined by whether the application functions as a channel shortener or requires independent output voltage levels. Verify compatibility with the host GPU's coupling method, as the device accommodates both AC and DC coupling configurations.

Part Context

The TDP1204 serves as a bridge between DisplayPort++ sources and HDMI 2.1 displays. It enables backward compatibility with HDMI 1.4b and 2.0b standards. The device integrates necessary signal conditioning and level shifting functions, reducing the need for discrete components in high-speed display interface designs.
