TDP2004IRNQT

Overview

The TDP2004 is a four-channel linear redriver supporting DisplayPort 2.1 up to 20Gbps and AC coupled HDMI 2.1 up to 12Gbps. It operates on a single 3.3V supply with active power consumption of 160mW per channel. The device provides 19dB equalization at 20Gbps, maintaining 1.8V DC linearity and 1.08V AC linearity. Electrical performance includes -15dB Rx return loss, -16dB Tx return loss, -60dB NEXT, and -43dB FEXT. Additive random jitter is limited to 70fs. Latency is 130ps typical. Configuration is available via pin-strap or SMBus/I2C, offering 18 EQ boost settings and 5 flat gain levels.

Feature Summary

Protocol agnostic linear equalizer supporting most AC coupled interfaces up to 24Gbps
Transparent to DisplayPort 1.4 and HDMI 2.1 link training for optimum electrical link
Internal voltage regulator provides immunity to supply noise

Applications

Desktop PC or motherboard
Docking stations
TV, gaming, home theater, and entertainment systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and package configuration. Confirm that the required I2C pull-up resistors and decoupling capacitors are included in the system design. Ensure the PCB layout adheres to the thermal dissipation guidelines provided in the datasheet.

Selection Notes

Select the TDP2004I variant for industrial applications requiring operation between -40°C and 85°C. Choose the standard TDP2004 for commercial environments operating between 0°C and 70°C. Consider the 40-pin WQFN package dimensions when designing the footprint. Verify that the system supports the necessary pin-strap resistor values or I2C interface requirements.

Part Context

This component belongs to Texas Instruments' family of high-speed signal conditioning devices designed for display interfaces. It functions as a linear repeater to extend trace lengths and maintain signal integrity in high-bandwidth video transmission paths.
