TDP2044RNQT

Overview

The TDP2044RNQT is a four-channel linear redriver supporting DisplayPort 2.1 at data rates up to 20Gbps (UHBR20). It features an integrated cross-point mux for USB Type-C Alt Mode applications, excluding USB 3.x. The device operates on a single 3.3V supply with active power consumption of 160mW per channel. Key electrical parameters include 19dB equalization boost, 70fs additive random jitter, and 100ps propagation delay. It utilizes continuous-time linear equalizers (CTLE) and is housed in a 4mm × 6mm WQFN-40 package.

Feature Summary

Supports DisplayPort 2.1 up to 20Gbps with integrated cross-point mux for USB Type-C Alt Mode
Features programmable CTLE with 18 EQ boost and 5 flat gain settings via pin-strap or I2C
Provides low latency and transparency to DisplayPort link training protocols
Includes internal voltage regulator for immunity to supply noise

Applications

Desktop PC motherboards
Docking stations
Flat panel monitors
TV and home theater systems

Procurement Notes

Verify the specific suffix 'RNQT' corresponds to the WQFN-40 package and commercial temperature range (0°C to 70°C). Confirm that the ordering part number matches the required tape-and-reel packaging configuration. Ensure compatibility with the intended system's I2C address settings and strap pin requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring high-bandwidth signal integrity over lossy PCB traces or cables. It is suitable for USB Type-C ports strictly using DP Alt Mode without USB 3.x multiplexing. Consider the TDP2044I variant if industrial temperature ranges (-40°C to 85°C) are required instead of the commercial grade.

Part Context

This device belongs to Texas Instruments' TDP2044 series of DisplayPort redrivers. It is designed to extend the reach of high-speed digital video interfaces by compensating for insertion loss. The RNQT designation indicates the specific package type and reel quantity configuration offered by the manufacturer.
