TDP2044IRNQT

Overview

The TDP2044IRNQT 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, specifically designed for DP-only source or sink configurations without USB 3.x support. The device operates on a single 3.3V supply with active power consumption of approximately 160mW per channel. It provides 19dB equalization boost and maintains low additive random jitter of 70fs. The component supports pin-strap, I2C, or EEPROM programming for configuration. It is rated for industrial operating temperatures ranging from –40°C to +85°C.

Feature Summary

• Supports DisplayPort 2.1 link rates up to 20Gbps with integrated cross-point mux for USB Type-C Alt Mode
• Features continuous-time linear equalizers (CTLE) with programmable high-frequency boost and flat gain settings
• Transparent to DisplayPort link training protocols while preserving transmit preset signal characteristics
• Offers multiple configuration modes including pin-strap, SMBus/I2C primary with external EEPROM, and SMBus/I2C secondary

Applications

• Desktop PC motherboards and video sources
• Docking stations and portable computing devices
• Flat panel monitors and entertainment systems

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to 85°C) compared to the commercial variant. Confirm the 'RNQT' suffix corresponds to the WQFN-40 package and reel packaging format. Ensure compatibility with the required 3.3V supply voltage and check for necessary external pull-up resistors for I2C/SMBus interfaces.

Selection Notes

Select this component for designs requiring high-performance signal conditioning for DisplayPort 2.1 UHBR20 links. The integrated cross-point mux simplifies USB-C Alt Mode routing by eliminating external switching components. Consider the industrial temperature rating if the application environment exceeds standard commercial limits. Verify that the system does not require simultaneous USB 3.x data transmission over the same lanes.

Part Context

This part belongs to the TDP2044 family of four-channel linear redrivers. The 'I' suffix denotes the industrial temperature range variant, distinct from the standard commercial version. It is part of Texas Instruments' portfolio of display interface solutions designed to extend trace lengths and maintain signal integrity in high-speed digital video applications.
