TDP1204IRNQR

Overview

The TDP1204IRNQR is a 12-Gbps HDMI 2.1 hybrid redriver and level shifter manufactured by Texas Instruments, designed for industrial temperature ranges (-40°C to 85°C). It supports AC-coupled or DC-coupled inputs and outputs, enabling backward compatibility with HDMI 1.4b and 2.0b standards. The device accommodates HDMI 2.1 Fixed Rate Link (FRL) configurations at data rates of 3, 6, 8, 10, and 12 Gbps across three or four lanes. Key electrical parameters include a single 3.3-V power supply requirement, an integrated HPD level shifter supporting 1.8-V and 3.3-V LVCMOS levels, and programmable receiver equalization up to 12 dB at 6 GHz. Power consumption varies significantly based on mode: active limited mode dissipates approximately 575 mW at 12 Gbps FRL, while linear mode consumes around 220 mW under similar conditions.

Feature Summary

• Hybrid redriver architecture supporting both source and sink applications via configurable linear or limited modes
• Integrated Hot Plug Detect (HPD) level shifter compatible with 1.8-V and 3.3-V logic levels
• Programmable receiver equalizer providing up to 12 dB gain at 6 GHz for signal integrity optimization
• Supports full lane swapping on main data lanes and DDC snooping for link configuration

Applications

• Industrial-grade notebooks and desktop computers requiring extended temperature operation
• Professional audio, video, and signage systems operating in harsh environments
• Docking stations and hubs interfacing DisplayPort++ sources with HDMI 2.1 displays
• Gaming consoles and home theater entertainment centers demanding high-bandwidth transmission

Procurement Notes

Verify the 'I' suffix confirms the industrial temperature range specification (-40°C to 85°C) distinct from commercial variants. Confirm the 'RNQ' package designation matches the required 40-pin WQFN footprint. Ensure procurement channels provide original manufacturer documentation to validate RoHS compliance and lead times against current production schedules.

Selection Notes

Select this component when system design requires operation below 0°C or above 70°C ambient temperatures. Choose the TDP1204IRNQR over commercial versions if the application environment exceeds standard commercial limits. Verify that the 3.3-V single supply rail aligns with the system's power distribution network before finalizing the bill of materials.

Part Context

This part belongs to the TDP1204 family of display interface ICs from Texas Instruments. The 'I' suffix specifically denotes the industrial temperature grade variant, differentiating it from the standard commercial version which operates between 0°C and 70°C. Both variants share identical pinouts, electrical characteristics, and functional capabilities within their respective thermal envelopes.

Replacement Considerations

Direct replacements must match the 40-pin WQFN package and support 12-Gbps HDMI 2.1 FRL. Verify that any substitute component offers equivalent industrial temperature ratings and integrated HPH/DDC shifting capabilities to maintain board layout compatibility without redesign.
