Product Overview
The TUSB1064RNQR is a low-power sink-side USB Type-C Alt Mode linear redriver crosspoint switch from Texas Instruments. It supports USB 3.1 Gen 2 (10 Gbps) and DisplayPort 1.4 HBR3 (8.1 Gbps per lane), offering protocol-agnostic signal routing for USB-only, 2-lane DP+USB or full 4-lane DP modes. Integrated adjustable CTLE equalization compensates cable and PCB signal loss without interfering with DP link training, with auto LFPS de-emphasis for USB-IF certification and full hot-plug support. Packaged in compact thermally enhanced 40-WQFN (4mm×6mm), it serves as core signal conditioning hardware for Type-C docks, monitors, VR peripherals and mobile expansion modules.
Core Advantages
Ultra-High-Speed Multimode Crosspoint Routing
Natively supports USB 3.1 Gen 2 (10Gbps) and DisplayPort 1.4 HBR3 (8.1Gbps/lane) simultaneously over single Type-C sink port, compatible with VESA C/D/E pin assignments without bandwidth throttling.
Adjustable CTLE Linear Equalization
Integrates multi-stage programmable continuous time linear equalization up to 12dB at 5GHz, effectively compensates ISI and channel loss to reduce jitter and bit error rate for long trace/cable designs.
Dual Configuration Control (GPIO / I2C)
Flexible setup via hardware pin strapping or system I2C registers, supporting fast mode switching for multi-scenario peripheral attachment layouts.
Low Power Operation & Transparent Link Training
TI low-power silicon architecture delivers minimal active draw, auto enters ultra-low quiescent sleep when upstream disconnects; fully transparent to DisplayPort link training without handshake interruption.
Certified Compliance & Hot-Plug Support
Built-in automatic LFPS de-emphasis to pass official USB-IF certification, full hot-plug tolerant design for live Type-C peripheral swapping.

Frequently Asked Questions
Q1: Is your currently available stock of the TUSB1064RNQR redriver 100% genuine and authentic?
A: Yes, we guarantee that all TUSB1064RNQR units in our warehouse are 100% brand-new, factory-original products directly from Texas Instruments. Every batch passes visual pin checks and is safely dispatched inside original anti-static pocket tape and reel configurations to protect pin-pad coplanarity.
Q2: What is the main structural difference between a linear redriver and a digital retimer?
A: A linear redriver like the TUSB1064RNQR applies Continuous Time Linear Equalization (CTLE) to boost and clean the incoming analog signal, correcting for PCB path losses without changing packet structures or interrupting link training. A retimer, by contrast, drops the signal down to digital bits via a Clock and Data Recovery (CDR) block to retransmit a totally fresh wave, which adds latency and configuration complexity compared to the lean, low-latency layout of a redriver.
Q3: How does the TUSB1064RNQR adapt to different cable lengths connected to the Type-C sink port?
A: The chip features dedicated hardware configuration pins and programmable internal I2C registers. This permits hardware engineers to adjust the gain parameters of the internal linear equalizer to match the precise attenuation curves of long board lines or heavy external Type-C sink cables.
Q4: How can our physical engineering group get formal component engineering drawings or request bulk wholesale pricing tiers?
A: Please complete the Quick Inquiry form on this webpage with your target quantities. Our application support desk will process your technical and supply criteria and reply with full data assets within 24 hours.
