Product details
Overview
TUSB217ARWBR from Texas Instruments is a USB 2.0 high-speed signal conditioner with integrated BC 1.2 DCP/CDP controllers, designed to restore signal integrity in lossy channels. It delivers edge and DC boost (4 selectable levels), RX pre-equalization (3 settings), operates from 2.3–6.5 V, supports up to 5-m cable compliance, and maintains zero added latency for HS signaling.
For engineers reviewing the TUSB217ARWBR datasheet, TUSB217ARWBR pinout, TUSB217ARWBR application, or TUSB217ARWBR equivalent, this page provides verified electrical specs, validated daisy-chain capability, confirmed BC 1.2 controller behavior, real-world eye mask compliance data, and precise thermal metrics for industrial and consumer USB host/device designs.
Technical Context
The TUSB217ARWBR implements a patented dual-stage compensation architecture: edge boost sharpens transition edges while DC boost restores static voltage levels-both configurable via external BOOST pin resistor values (160 Ω to open). Its tri-level RX_SEN pin selects one of three pre-equalization gains to counteract ISI jitter induced by long cables or high-loss PCB traces.
It integrates a BC 1.2-compliant charging controller that dynamically switches between Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) modes based on the logic state of the DCP/CDP pin (internal 500 kΩ pull-up), with automatic VBUS toggle coordination required for mode re-detection. The device remains host- and device-agnostic, preserving LS/FS signal characteristics while conditioning only HS traffic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3–6.5 V - Enables direct integration into 3.3 V or 5 V USB systems without LDO, including battery-powered devices with wide input range. |
| HS Bit Rate | 480 Mbps - Fully compliant with USB 2.0 High-Speed specification; no packet timing alteration or propagation delay added. |
| Boost Levels | 4 settings via BOOST pin - Configurable edge+DC boost strength (Level 0–3) using external pulldown resistors for precise channel loss matching. |
| RX Equalization | 3 settings via RX_SEN pin - Selects low/medium/high pre-equalization gain to compensate inter-symbol interference in 28–24 AWG cables up to 10 m with daisy-chaining. |
| BC 1.2 Support | Integrated DCP & CDP controllers - Dynamically enabled via DCP/CDP pin; internal pull-up defaults to CDP mode when floating. |
| Package | X2QFN-12 (RWB) - 1.6 mm × 1.6 mm, 0.4 mm pitch, thermally optimized for compact USB layout with RθJA = 137.4 °C/W. |
| Operating Temp | 0°C to 70°C - Validated for standard commercial applications including docking stations, tablets, and active cables. |
Pinout & Package
X2QFN-12 (RWB) package: 1.60 mm × 1.60 mm body, 0.4 mm pitch, wettable flank leads for automated optical inspection. Exposed thermal pad improves power dissipation in high-traffic HS operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1P / D1M | HS differential input (upstream) | Connects to USB host/hub transceiver; bidirectional, preserves LS/FS pass-through in non-HS modes. |
| D2P / D2M | HS differential output (downstream) | Drives USB connector; conditioned HS signal with boosted eye opening and reduced ISI jitter. |
| DCP/CDP | BC 1.2 mode select input | Low = DCP mode (charger-only); High = CDP mode (data + charging); internal 500 kΩ pull-up defaults to CDP. |
| RX_SEN/ENA_HS | Tri-level config / HS status output | Pulled high/low/floating for RX equalization level; outputs ENA_HS high when HS link established. |
| BOOST | Signal boost control input | External pulldown resistor sets combined edge+DC boost level (0–3); floating = Level 3. |
| RSTN | Active-low shutdown enable | Drives device into ultra-low ISHUTDN = 60–115 µA; DP/DM remain continuous in shutdown. |
| CD | Connection detect output | Asserts high on LS/FS/HS attach; goes low only during HS compliance test mode. |
| VCC / GND | Power supply terminals | VCC accepts 2.3–6.5 V; GND reference for all analog/digital functions and ESD protection network. |
Key Features

| Tablet USB Host Interface | Smart TV USB Peripheral Hub |
|
Use Scenario: A tablet with USB OTG capability hosts a USB flash drive and keyboard simultaneously through a micro-AB receptacle. IC Role / Device Role / Timing Role: TUSB217ARWBR conditions HS traffic between the tablet's PHY and the micro-AB port, while its BC 1.2 controller negotiates charging current with attached peripherals. Use Value: Maintains HS data throughput during concurrent charging negotiation, preventing link training failures caused by signal degradation on compact internal routing. |
Use Scenario: A 4K smart TV includes a rear-panel USB hub supporting media playback from flash drives and firmware updates via USB stick. IC Role / Device Role / Timing Role: TUSB217ARWBR buffers and conditions HS signals between the SoC's USB controller and the hub's downstream ports, compensating for long flex-cable runs and EMI filtering components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB216IRWBR | Fixed 3-level DC boost only; no RX pre-equalization; 3.3 V supply only; no BC 1.2 controller. | Limited to shorter (<4 m), lower-loss channels; requires external charging IC for BC 1.2 compliance. | Select when cost-sensitive, fixed-boost applications omit BC 1.2 and require simpler configuration. |
| TUSB214IRWBR | 3-level DC boost + tandem AC boost; no RX equalization; 3.3 V only; no BC 1.2 controller. | Suitable for medium-loss channels (≤4 m, 28 AWG); lacks dynamic charging mode support and far-end eye extension. | Choose for legacy designs needing proven tandem boost but no equalization or charging integration. |
Compared with TUSB216IRWBR and TUSB214IRWBR, the TUSB217ARWBR uniquely combines programmable edge+DC boost, 3-level RX pre-equalization, and integrated BC 1.2 DCP/CDP control in a single 2.3–6.5 V device-enabling longer cables, higher-loss PCBs, and simplified charging architecture without external controllers.

FAQ
What is the maximum cable length supported by the TUSB217ARWBR?
The TUSB217ARWBR supports up to 5 meters of 28 AWG cable in standalone configuration while maintaining USB 2.0 high-speed near-end eye compliance. When two TUSB217ARWBR devices are daisy-chained-one at each end-the solution extends support to 10-meter cables with 24–28 AWG conductors, compensating for both AC and DC channel loss.
Does the TUSB217ARWBR alter USB packet timing or add latency?
No, the TUSB217ARWBR does not alter packet timing or introduce propagation delay or latency. Its patented signal conditioning architecture restores signal integrity by boosting edge transitions and DC levels without buffering or retiming-ensuring bit-for-bit transparency and full USB 2.0 protocol compliance for all speeds (LS, FS, HS).
How does the BC 1.2 charging controller operate on the TUSB217ARWBR?
The TUSB217ARWBR integrates a BC 1.2-compliant charging controller that dynamically switches between Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) modes based on the logic level applied to the DCP/CDP pin (Pin 11). A low level selects DCP mode; a high level selects CDP mode. Internal 500 kΩ pull-up defaults to CDP when the pin is floating.
Can the TUSB217ARWBR be used in I²C configuration mode?
Yes, the TUSB217ARWBR supports I²C configuration via SDA (Pin 3) and SCL/CD (Pin 4) with 7-bit slave address 0x2C. In I²C mode, registers such as EDGE_BOOST (0x1), DC_BOOST (0xE), and RX_SEN (0x25) can be programmed for fine-grained control of boost levels and equalization-enabling precise tuning beyond resistor-based configuration.
What is the thermal performance of the TUSB217ARWBR in its X2QFN package?
The TUSB217ARWBR in the RWB X2QFN-12 package has a junction-to-ambient thermal resistance (RθJA) of 137.4 °C/W under standard JEDEC conditions. Its exposed thermal pad and low RθJB = 67.2 °C/W enable effective heat dissipation in compact layouts, supporting continuous 480 Mbps operation within the 0°C to 70°C ambient range without derating.
