TUSB215RGYT - USB 2.0 HS Signal Conditioner | Texas Instruments
料号： TUSB215RGYT ✓ 量产中TUSB215RGYT 概述
A USB signal conditioner is an interface IC that restores signal integrity through lossy interconnect while adding the functions required by a USB port. The TUSB215 family is intended for systems where cable loss, connector transitions, PCB routing, or other channel impairments can degrade USB data signals. Its support for host or device use and interchangeable D+ and D− data paths makes it useful across common USB port architectures.
The TUSB215RGYT includes DC boost, an integrated CDP, and a VBUS supply. Its USB BC1.2 CDP controller can be configured by pin strap or I²C, providing a practical way to identify a downstream-facing port and coordinate charging behavior. The device also supports daisy chaining, which can extend reach in high-loss applications. TI specifies support for up to 5 m of pre-channel cable or 2 m of post-channel cable.
The device supports low-speed, full-speed, and high-speed signaling. Its dual data-path implementation permits D1P/M and D2P/M interchangeability, reducing sensitivity to which host or device lane is connected. This is particularly useful in reusable equipment, docking systems, and port designs where source and sink roles can change.
Typical uses include USB 2.0 docking stations, laptop and tablet accessories, industrial data acquisition equipment, peripheral interfaces, and test systems. The integrated CDP and VBUS functions can simplify a compliant USB port design, while the signal-conditioning stage is intended to preserve data integrity over longer or less controlled interconnect.
PCB implementation should preserve the high-speed differential pair as a controlled-impedance route and place decoupling close to the supply pins. Review the pin-description and layout guidance in the manufacturer datasheet before assigning tracks or selecting external components. Verify that the selected cable length and channel placement comply with the device’s stated pre-channel and post-channel limits.

典型应用
TUSB215RGYT 适用于 6 应用s: USB 2.0 Docking Stations, Laptop and Tablet Peripherals, Industrial Data Acquisition, USB Test and Measurement Systems, Printers and USB Peripherals, Multi-Port USB Equipment.
USB 2.0 Docking Stations
The TUSB215RGYT fits USB 2.0 docking stations where connector transitions and internal routing can weaken the D+ and D− high-speed pair. Its signal-conditioning function supports Low-Speed, Full-Speed, and High-Speed signaling up to 480 Mbit/s, while DC boost helps maintain the data path. The integrated BC1.2 CDP and VBUS supply also consolidate common downstream-port functions. TI specifies daisy-chain support and up to 5 m of pre-channel or 2 m of post-channel cable, making channel placement an important design consideration.
推荐
Laptop and Tablet Peripherals
The TUSB215RGYT can improve a USB peripheral connection when a device uses an internal cable, connector, or compact PCB route between the host controller and an external USB port. Support for interchangeable D1P/M and D2P/M paths allows the data lanes to be routed according to the mechanical connector orientation. Its 480 Mbit/s high-speed capability preserves USB 2.0 performance, and the integrated CDP and VBUS functions are useful in downstream-facing accessory designs where port behavior must be defined more efficiently.
推荐
Industrial Data Acquisition
Industrial measurement equipment often connects USB peripherals through cables, panel connectors, and long PCB routes that can degrade high-speed signal integrity. The TUSB215RGYT provides a dedicated USB 2.0 signal-conditioning path with DC boost and support for LS, FS, and HS operation. Its interchangeable data-path design simplifies implementation where host and device roles may vary. For deployed equipment, confirm the operating-temperature and qualification requirements, then follow the manufacturer layout guidance to maintain controlled impedance and minimize discontinuities.
推荐
USB Test and Measurement Systems
The TUSB215RGYT is suitable for USB test equipment, interface adapters, and portable measurement systems where an internal USB route may be less controlled than a short direct connection. The device conditions the USB data path and supports the three USB 2.0 signaling rates, with a 480 Mbit/s high-speed mode for data-intensive instruments. The integrated CDP and VBUS supply can simplify a downstream port, while daisy-chain capability provides a way to build signal-conditioning stages for high-loss channels. Cable placement should follow the stated pre-channel and post-channel limits.
推荐
Printers and USB Peripherals
The TUSB215RGYT can support USB 2.0 peripheral designs that connect through an internal harness or a user-replaceable cable. High-Speed operation up to 480 Mbit/s preserves the data throughput required for imaging, storage, and general-purpose USB peripherals, while DC boost supports signal transmission through impaired channels. Interchangeable D1P/M and D2P/M routing simplifies connector orientation. When the device also acts as a downstream port, the integrated CDP and VBUS supply reduce the number of dedicated port-support functions needed nearby.
推荐
Multi-Port USB Equipment
The TUSB215RGYT can be used in equipment with multiple USB ports, including universal docks, service instruments, and configurable peripheral systems. Its host- and device-agnostic operation supports flexible port roles, while the integrated CDP and VBUS supply are useful when the port must present downstream charging behavior. Daisy-chain support enables a scalable approach to long or lossy channels, subject to TI’s 5 m pre-channel and 2 m post-channel limits. Board-level planning should identify each conditioner’s channel position before routing the USB differential pairs.

关键差异点
- Combines USB signal conditioning and downstream charging support （对比 TUSB213RGYR)
- Supports programmable or pin-strap CDP configuration （对比 TUSB213QRGYRQ1)
- Retains the complete TUSB215 feature family in an automotive-designated option （对比 TUSB213QRGYTQ1)
设计说明
Route the USB high-speed differential pair as a controlled-impedance structure with closely matched spacing and minimal stubs. Keep the TUSB215RGYT input and output connections short relative to the lossy channel, and place the device at the boundary identified by the channel plan. Use the manufacturer layout example as the basis for layer transitions, via placement, and the relationship between the USB data path and the exposed pad.
Follow the manufacturer recommendations for VBUS, supply decoupling, and configuration pins. The TUSB215RGYT integrates a VBUS supply and a CDP, so the power path must be evaluated as part of the complete USB port rather than as a separate data-only circuit. Confirm whether the application uses pin-strap or I²C CDP configuration, and preserve the required logic levels and timing before enabling the port.
Do not treat a shared VQFN-14 package as proof of functional drop-in compatibility. The TUSB213-family options do not integrate the same CDP and VBUS feature set as the TUSB215RGYT, while the Q1 variants add automotive ordering characteristics. Before substitution, compare the complete pin-description table, exposed-pad connection, configuration method, charging behavior, and the manufacturer application circuit.
Place the signal conditioner according to the actual cable and PCB loss rather than only by connector distance. TI specifies support for up to 5 m of pre-channel cable or 2 m of post-channel cable. Validate the deployed channel at 480 Mbit/s, including cable type, connectors, board transitions, and adjacent structures, and use eye-diagram or compliance testing to confirm adequate margin.
