TDP0604RNQR

Overview

The TDP0604RNQR is a HDMI 2.0 hybrid redriver supporting 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 with VIO ranging from 1.14 V to 3.6 V depending on the logic level. It is available in a 40-pin WQFN package measuring 4 mm × 6 mm with a 0.4 mm pitch. Active power consumption is 215 mW at 6 Gbps limited mode, while power-down consumption is 0.55 mW.

Feature Summary

• Supports AC-coupled or DC-coupled inputs and outputs for flexible system integration
• Integrated HPD level shifter accommodating both 1.8-V and 3.3-V LVCMOS levels
• Includes DDC buffer providing capacitance isolation and level shifting down to 1.2-V
• Enables full lane swapping on main lanes and DDC snooping for link configuration

Applications

• Notebooks and desktops
• TV systems
• Home theater and entertainment devices
• Gaming systems
• Docking stations

Procurement Notes

Verify the specific ordering suffix RNQR against the manufacturer's current orderable addendum to confirm package type and temperature grade. Ensure the procurement source provides valid traceability documentation. Confirm that the component matches the exact part number specifications before finalizing orders to avoid compatibility issues with host systems.

Selection Notes

Select this component when designing HDMI 2.0 or DP++ interfaces requiring signal integrity restoration up to 6 Gbps. Choose the limited redriver mode for source applications to ensure compliant output levels independent of GPU voltage. Opt for linear redriver mode in sink applications to maintain transparency during link training. Verify I/O voltage requirements match the target system's logic levels.

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 display receptacles, handling high-speed differential signaling. The device integrates necessary level shifting and buffering functions typically found in discrete solutions, reducing overall system complexity and board space requirements.

FAQ

Can the TDP0604 operate with both AC-coupled and DC-coupled connections?

Yes, the high-speed differential inputs and outputs can be configured for either AC-coupling or DC-coupling, qualifying it for use as a DP++ to HDMI level shifter or an HDMI redriver.

What is the maximum receiver equalization gain provided by the device?

The programmable receiver equalizer provides up to 12 dB of gain at 3 GHz.

How does the integrated HPD level shifter function?

The HPD level shifter shifts the 5-V HPD signal to either 1.8-V or 3.3-V. The output can be configured for push-pull, pull, or open-drain operation.
