TDP2004IRNQR

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 features a continuous-time linear equalizer (CTLE) providing up to 19dB boost at 10GHz, with low additive random jitter of 70fs. Input and output return losses are -15dB and -16dB respectively, while crosstalk is limited to -60dB NEXT and -43dB FEXT. Propagation delay is typically 130ps. Configuration is available via pin-strap, I2C, or EEPROM programming, offering 18 EQ boost and 5 flat gain settings.

Feature Summary

• Protocol agnostic linear equalization supporting most AC coupled interfaces up to 24Gbps
• Transparent operation during DisplayPort 1.4 and HDMI 2.1 link training
• Internal voltage regulator provides immunity to supply noise
• Configurable via pin-strap, SMBus/I2C, or external EEPROM

Applications

• Desktop PC motherboards
• PCs, notebooks, and tablets
• Docking stations
• TVs, gaming consoles, and home theater systems
• Flat panel monitors

Procurement Notes

Verify the specific ordering suffix for temperature range requirements. The standard TDP2004 supports commercial temperatures from 0°C to 70°C, while the TDP2004I variant supports industrial temperatures from -40°C to 85°C. Confirm package availability in the 4mm x 6mm WQFN format. Ensure compatibility with system power supply specifications and interface protocols before procurement.

Selection Notes

Select the TDP2004 for applications requiring high-speed signal integrity over lossy interconnects like PCB traces or cables. Choose the I-suffix version if the operating environment exceeds commercial temperature limits. Consider the configuration method; use pin-strap for static setups or I2C/EEPROM for dynamic adjustment. Evaluate the required equalization depth against the 19dB maximum boost capability.

Part Context

The TDP2004 belongs to Texas Instruments' family of high-performance linear repeaters designed for next-generation display interfaces. It complements other redrivers by offering support for UHBRx rates in DisplayPort 2.1 and high-bandwidth HDMI 2.1 sources. The device addresses signal degradation challenges in modern computing and entertainment platforms.
