TDP2044IRNQR

Overview

The TDP2044IRNQR is a four-channel linear redriver with an integrated cross-point mux, designed for USB Type-C Alt Mode applications supporting DisplayPort 2.1 up to 20Gbps (UHBR20). It operates on a single 3.3V supply with active power consumption of 160mW per channel. The device features continuous-time linear equalizers (CTLE) providing up to 19dB boost at 10GHz. Electrical performance includes -15/-16dB Rx/Tx return loss and 70fs additive random jitter. Configuration is supported via pin-strap, I2C, or EEPROM programming with 18 EQ boost and 5 flat gain settings. It operates within a temperature range of -40°C to 85°C in a 4mm x 6mm WQFN 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 high linearity for excellent signal integrity
Transparent to DisplayPort link training protocols
Configurable via pin-strap, SMBus/I2C, or external EEPROM

Applications

Desktop PC motherboards
PC, notebooks, and tablets
Docking stations
TV, gaming, home theater, and entertainment systems
Flat panel monitors

Procurement Notes

Verify the 'I' suffix indicates the industrial temperature grade (-40°C to 85°C), distinct from the commercial variant. Confirm the RNQR suffix corresponds to the 40-pin WQFN package and reel packaging format. Ensure compatibility with USB Type-C DP-only source or sink designs, as the device does not support USB 3.x data paths.

Selection Notes

Select this component for high-speed video links requiring transparent equalization without protocol dependency. The integrated cross-point mux simplifies routing in compact USB-C designs. Consider the low additive jitter and high linearity for maintaining signal quality over lossy PCB traces or cables. Verify that the system design accommodates the required I2C pull-up resistors if using secondary mode configuration.

Part Context

The TDP2044 belongs to Texas Instruments' family of DisplayPort linear redrivers. The IRNQR designation specifies the industrial temperature range variant packaged in a 40-pin WQFN. This part complements other interface solutions by providing robust signal conditioning for next-generation display standards.
