TDP0604RNQT

Overview

The TDP0604RNQT is a hybrid redriver supporting HDMI 2.0 data rates up to 6 Gbps, backwards compatible with HDMI 1.4b. It supports dual-mode DisplayPort (DP++) and features programmable receiver equalization up to 12 dB at 3 GHz. The device operates on a single 3.3-V power supply and includes an integrated HPD level shifter for 1.8-V or 3.3-V LVCMOS levels, plus a DDC buffer supporting levels as low as 1.2 V. It offers I2C or pin-strap configuration, full lane swap capability, and DDC snooping. Power consumption is 215 mW in active limited mode and 0.55 mW in power-down. It is housed in a 40-pin WQFN package.

Feature Summary

• Hybrid redriver architecture supporting both linear and limited modes for source and sink applications
• Integrated hot plug detect (HPD) level shifter and Digital Display Control (DDC) buffer
• Programmable receiver equalizer with configurable CTLE maps via I2C or pin straps
• Supports AC-coupled or DC-coupled inputs and outputs for DP++ to HDMI conversion

Applications

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

Procurement Notes

Verify the specific ordering suffix 'RNQT' corresponds to the required tape-and-reel packaging format and commercial temperature range (0°C to 70°C). Confirm that the component matches the exact datasheet revision SLLSFJ8A–December 2021–Revised June 2023 to ensure accurate pinout and electrical characteristics. Cross-reference the manufacturer part number with official Texas Instruments documentation before finalizing procurement orders.

Selection Notes

Select this component when designing interfaces requiring signal integrity restoration for HDMI 2.0 or DP++ links up to 6 Gbps. Choose the limited redriver mode for source applications to ensure compliant output levels independent of GPU voltage. Opt for linear mode in sink applications to maintain transparency during link training. Ensure the design accommodates the 40-pin WQFN thermal pad requirements for adequate heat dissipation under maximum load conditions.

Part Context

This component belongs to the TDP0604 series of display interface ICs manufactured by Texas Instruments. It serves as a bridge between graphics processing units and HDMI receptacles, facilitating signal translation and regeneration. The RNQT suffix indicates the specific reel packaging variant intended for automated surface-mount assembly processes.
