Product details
Overview
TUSB215QRGYTQ1 from Texas Instruments is an automotive-qualified USB 2.0 High-Speed signal conditioner with integrated BC 1.2 Charging Downstream Port (CDP) controller. It compensates for inter-symbol interference (ISI) in lossy channels, supports LS/FS/HS signaling without altering low-speed signals, delivers up to 80 mV DC boost and four AC boost levels, and operates across –40°C to 105°C ambient temperature - enabling robust USB signal integrity in automotive infotainment head units.
For engineers reviewing the TUSB215QRGYTQ1 datasheet, TUSB215QRGYTQ1 pinout, TUSB215QRGYTQ1 application, or TUSB215QRGYTQ1 equivalent, key selection considerations include HS eye mask compliance support, pin-strapped or I²C-configurable AC/DC boost, CDP controller functionality for host-side charging handshaking, and AEC-Q100 Grade 2 qualification for automotive deployment.
Technical Context
The TUSB215QRGYTQ1 implements a patent-pending, host/device-agnostic signal conditioning architecture that preserves LS/FS signal integrity while applying programmable AC and DC gain exclusively to HS differential pairs (D1P/D1M, D2P/D2M). Its dual-channel topology allows flexible placement - either pre-connector (to pass near-end eye mask) or post-connector (to pass far-end eye mask) - with daisy-chain capability for high-loss applications.
It integrates a dedicated CDP controller supporting BC 1.2 handshake sequences, status flag outputs (CD, ENA_HS), and configurable I²C interface (7-bit address 0x2C) for runtime register access to ACB_LVL and DCB_LVL. The device enters shutdown mode when RSTN is asserted low, reducing current to ≤80 µA while maintaining full USB channel pass-through.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | USB 2.0 High-Speed (480 Mbps), OTG 2.0, and Battery Charging 1.2 CDP compliant - enables full protocol interoperability without host-side firmware changes. |
| AC Boost Levels | 4 selectable levels via external EQ pin pulldown resistor (0–6 kΩ) - tunes high-frequency gain to restore eye opening degraded by PCB trace or cable loss. |
| DC Boost Settings | 3-level pin-strapped DC offset (40/60/80 mV) on DC_BOOST pin - compensates for low-frequency attenuation in long cables or high-capacitance traces. |
| Operating Temp | –40°C to +105°C ambient (AEC-Q100 Grade 2) - validated for under-dash automotive environments with no derating required. |
| Power Consumption | ≤30 mA active HS current; ≤1.5 mA HS suspend; ≤80 µA shutdown - minimizes thermal load and supports always-on USB detection. |
| Signal Transparency | Zero impact on LS/FS signaling - maintains legacy device compatibility while enhancing only HS signal integrity. |
| ESD Robustness | ±2000 V HBM, ±500 V CDM - meets automotive ESD requirements without external protection diodes on DP/DM lines. |
Pinout & Package
VQFN-14 package (3.5 mm × 3.5 mm, 0.5 mm pitch) with exposed thermal pad for enhanced heat dissipation in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EQ | AC boost configuration input | Four-level AC gain selection via external pulldown resistor; sampled at RSTN de-assertion - enables static tuning without I²C. |
| D1P / D1M D2P / D2M |
HS differential I/O pairs | Interchangeable bidirectional ports - D1 side connects to host/hub, D2 side to connector; agnostic to host/device role. |
| DC_BOOST/ENA_HS | Tri-level DC gain input / HS mode flag output | Configures 40/60/80 mV DC boost at reset; outputs ENA_HS high upon successful HS handshake - provides real-time link status. |
| SCL/CD | I²C clock / connection detect output | In non-I²C mode: CD asserts high when DP/DM pull-up detected - replaces host-side enumeration logic for plug-in detection. |
| SDA | I²C data bidirectional | Enables dynamic reconfiguration of AC/DC boost registers (0x01, 0x0E) and CFG_ACTIVE control - supports field-tunable signal optimization. |
| RSTN | Active-low enable/reset | Holds device in ultra-low-power shutdown (≤80 µA) when low; requires ≥20 µs pulse width and stable VCC before de-assertion. |
| VREG | 1.8 V LDO output | Supplies internal core logic only during HS mode - requires 0.1 µF bypass capacitor to GND for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 2 qualification | Validated for automotive use from –40°C to +105°C ambient, with HBM H1C and CDM C3 ESD ratings - eliminates need for additional qualification testing. |
| USB BC 1.2 CDP controller | Performs D+–D− handshake sequences (SDP/CDP/DCP detection) autonomously - enables charging-aware USB ports on hosts lacking native BC support. |
| Daisy-chain capability | Multiple TUSB215QRGYTQ1 devices can be cascaded to compensate >5 m of pre-channel loss - extends reach beyond standard USB 2.0 limits. |
| HS/LS/FS signal agnosticism | Passes LS/FS traffic unchanged while applying boost only to HS signals - ensures backward compatibility with legacy peripherals. |
| Flexible placement topology | Supports both near-end (pre-connector) and far-end (post-connector) configurations - allows optimization for either USB-IF eye mask test point or system-level signal integrity. |

FAQ
What is the primary function of the TUSB215QRGYTQ1 in a USB 2.0 system?
The TUSB215QRGYTQ1 functions as a High-Speed signal conditioner that restores USB 2.0 HS signal integrity degraded by PCB trace loss, cable attenuation, or connector discontinuities. It applies programmable AC and DC boost exclusively to HS differential pairs while leaving LS/FS signals unaltered. Additionally, the TUSB215QRGYTQ1 integrates a BC 1.2 Charging Downstream Port (CDP) controller to manage charging handshakes - making it ideal for automotive head units and docking stations lacking native CDP support.
How does the TUSB215QRGYTQ1 support automotive qualification requirements?
The TUSB215QRGYTQ1 is AEC-Q100 qualified for Grade 2 operation (–40°C to +105°C ambient), with HBM ESD rating of ±2000 V and CDM rating of ±500 V. It undergoes rigorous stress testing including thermal cycling, humidity bias, and accelerated life testing per automotive standards. These qualifications are documented in the official TI production datasheet (SLLSF07), confirming its suitability for under-hood and in-cabin automotive applications without additional qualification effort.
Can the TUSB215QRGYTQ1 be configured without using I²C?
Yes, the TUSB215QRGYTQ1 supports full pin-strapped configuration: AC boost level is set via external pulldown resistor on the EQ pin, and DC boost level (40/60/80 mV) is selected using voltage thresholds on the DC_BOOST pin. These settings are latched at power-up or RSTN de-assertion and require no I²C interface. The TUSB215QRGYTQ1 defaults to mid DC boost (60 mV) and auto-selects maximum AC boost if EQ is left floating - enabling simple, low-pin-count integration.
What is the role of the CD and ENA_HS pins on the TUSB215QRGYTQ1?
The CD (Connection Detect) pin asserts high when a USB device is attached - detected via DP or DM pull-up resistor - providing plug-in status without host-side polling. The ENA_HS pin asserts high only after successful HS handshake (chirp J/K detection), indicating active 480 Mbps link establishment. Both are open-drain outputs with 2.4 V VOH and 0.4 V VOL, enabling direct interfacing with microcontroller GPIOs for real-time USB state monitoring in the TUSB215QRGYTQ1 design.
Does the TUSB215QRGYTQ1 support daisy-chaining for extreme channel loss compensation?
Yes, the TUSB215QRGYTQ1 supports daisy-chaining multiple units to compensate for >5 m of pre-channel loss - a capability explicitly documented in the TI datasheet as a scalable solution for high-loss applications. Each stage applies independent AC/DC boost, and the device's host/device-agnostic design ensures correct operation regardless of orientation (D1↔D2 swap). This eliminates the need for custom ASICs or complex FPGA-based equalization in extended automotive or industrial USB links.
