TDP1204RNQT

Overview

The TDP1204RNQT is a Texas Instruments HDMI 2.1 hybrid redriver supporting data rates up to 12 Gbps with backward compatibility for HDMI 1.4b and 2.0b. It accommodates both AC-coupled and DC-coupled high-speed differential inputs and outputs, enabling use as a DP++ to HDMI level shifter or HDMI redriver. The device supports HDMI 2.1 Fixed Rate Link (FRL) at 3, 6, 8, 10, and 12 Gbps across three and four lanes. Operating on a single 3.3-V supply, it features integrated HPD and DDC level shifters, programmable receiver equalization up to 12 dB at 6 GHz, and full lane swap capabilities. Available in a 40-pin WQFN package, it operates within commercial temperature ranges.

Feature Summary

• Hybrid redriver architecture supporting both linear and limited modes for source and sink applications
• Integrated Hot Plug Detect (HPD) and Digital Display Control (DDC) level shifters eliminating discrete components
• Programmable receiver equalizer with adaptive and fixed settings up to 12 dB at 6 GHz
• Supports I2C or pin-strap configuration for flexible system integration

Applications

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

Procurement Notes

Verify the specific ordering suffix RNQT corresponds to the WQFN 40-pin package and reel packaging format required for your assembly process. Confirm that the commercial temperature grade meets your environmental specifications. Ensure design compliance with the recommended operating conditions for VCC and VIO voltages to maintain signal integrity and device reliability during operation.

Selection Notes

Select the TDP1204RNQT when designing systems requiring DP++ to HDMI conversion or HDMI signal extension up to 12 Gbps. Choose this component if the application demands integrated level shifting for HPD and DDC lines to simplify the bill of materials. Consider the hybrid redriver's ability to operate in either linear or limited mode based on whether the design functions as a source or sink interface.

Part Context

The TDP1204 belongs to Texas Instruments' display interface IC portfolio, specifically designed for high-bandwidth video transmission. It complements other redriver and retimer solutions by offering a hybrid approach suitable for both source-side level shifting and sink-side signal conditioning. The device addresses the growing demand for HDMI 2.1 FRL support in modern consumer electronics and computing platforms.
