Product details
Overview
TUSB213QRGYRQ1 from Texas Instruments is an automotive-qualified USB 2.0 High-Speed signal conditioner IC designed to compensate for inter-symbol interference (ISI) loss in transmission channels. It supports LS/FS/HS signaling, delivers programmable AC boost (4 levels) and DC boost (40/60/80 mV), operates from 4.4 V to 5.5 V, and features I²C or pin-strapped configuration - enabling robust USB electrical compliance in infotainment head units and docking stations.
For engineers reviewing the TUSB213QRGYRQ1 datasheet, TUSB213QRGYRQ1 pinout, TUSB213QRGYRQ1 application, or TUSB213QRGYRQ1 equivalent, key selection criteria include HS eye mask margin recovery, AEC-Q100 Grade 2 qualification (–40°C to 105°C), ultra-low suspend current (0.76–1.5 mA), daisy-chain capability for high-loss channels, and host/device-agnostic D1P/D1M/D2P/D2M port interchangeability.
Technical Context
The TUSB213QRGYRQ1 implements a patent-pending signal conditioning architecture that preserves LS/FS signal integrity while applying adaptive equalization only to HS (480 Mbps) differential data. Its dual-path design allows D1 and D2 ports to be oriented either toward host/hub or connector without functional impact.
Configuration is supported via pin-strapping (EQ for AC boost, DC_BOOST for DC gain) or I²C (7-bit address 0x2C), with latched settings sampled at RSTN de-assertion. The device outputs status flags (CD for connection detection, ENA_HS for HS mode assertion) and provides a 1.8-V VREG LDO output enabled only during HS operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.4 V to 5.5 V - ensures compatibility with standard 5-V USB power rails and stable operation across automotive load-dump transients. |
| HS Bit Rate | 480.24 Mbps - fully compliant with USB 2.0 High-Speed specification and sufficient for passing USB-IF near/far-end eye mask tests. |
| AC Boost Levels | 4 selectable levels via EQ pin pulldown resistor - enables precise tuning of high-frequency gain to counteract PCB trace and cable loss. |
| DC Boost Settings | 40 mV / 60 mV / 80 mV - configurable via DC_BOOST pin strap to restore signal baseline offset degraded by channel capacitance and resistance. |
| HS Suspend Current | 0.76–1.5 mA - minimizes standby power in automotive systems where USB ports remain powered during ignition-off states. |
| Ambient Temp Range | –40°C to +105°C - meets AEC-Q100 Grade 2 requirements for under-hood and dashboard-mounted infotainment modules. |
| ESD Rating | ±2000 V HBM - protects against handling and system-level electrostatic discharge in production and field environments. |
Pinout & Package
VQFN-14 (RGY) package, 3.5 mm × 3.5 mm, 1.0 mm max height, with exposed thermal pad - optimized for compact automotive PCB layouts and efficient heat dissipation in thermally constrained enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EQ | AC boost configuration input | Four-level external pulldown resistor selects AC gain; sampled once at reset - enables passive tuning without firmware. |
| D1P / D1M / D2P / D2M | HS differential I/O pairs | Port-agnostic bidirectional HS lanes; D1 and D2 sides swappable in layout - simplifies routing in host-to-connector or hub-to-cable configurations. |
| DC_BOOST/ENA_HS | Configurable DC gain input / HS mode flag output | Tri-level input sets DC boost voltage; transitions to open-drain output asserting ENA_HS when HS handshake completes. |
| SCL/CD | I²C clock / connection detect output | In I²C mode: clock line; in pin-strapped mode: CD flag asserted on DP/DM pull-up detection - supports platform-level USB attach sensing. |
| RSTN | Active-low reset and enable | Pulled up internally (500 kΩ); must be held low until VCC ≥ 4.4 V - ensures reliable power-on initialization and shutdown control. |
| VREG | 1.8-V LDO output | Supplies internal core only during HS mode; requires 0.1-µF bypass capacitor - eliminates need for external 1.8-V rail in cost-sensitive designs. |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0/OTG/BC 1.2 compatibility | Full protocol transparency - no impact on LS/FS signaling or BC charging handshakes; passes USB-IF compliance with minimal layout changes. |
| Daisy-chain capability | Enables cascaded placement (e.g., SoC → TUSB213QRGYRQ1 → connector → cable → device) to recover >5 dB channel loss - critical for long automotive harnesses. |
| Host/device-agnostic ports | D1P/D1M and D2P/D2M are functionally identical - eliminates orientation constraints and reduces BOM variants in multi-platform designs. |
| Ultra-low HS suspend power | Sub-1.5 mA current draw in HS suspend state - extends battery life in portable docks and reduces thermal load in sealed infotainment enclosures. |
| AEC-Q100 Grade 2 qualification | Validated for –40°C to +105°C ambient, HBM H1C, CDM C3 - meets automotive reliability requirements without derating or additional qualification effort. |
Applications
| Automotive Infotainment Head Unit | Notebook Docking Station |

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 |
|---|---|---|---|
| TS3USB221ERSER | Passive 2-channel USB 2.0 switch with 6 Ω on-resistance; no signal boosting or DC/AC equalization. | Used for USB path selection only - cannot recover channel loss or improve eye mask margin. | Select only when signal integrity is already adequate and multiplexing is the primary requirement. |
| USB2514B-AEZG | USB 2.0 hub controller with integrated PHY; includes packet retry, transaction translation, and 4-port expansion. | Provides full hub functionality but occupies larger footprint and requires firmware; not a drop-in signal conditioner replacement. | Choose when port expansion and protocol-aware features outweigh size, cost, and simplicity advantages of TUSB213QRGYRQ1. |
Compared with TS3USB221ERSER and USB2514B-AEZG, the TUSB213QRGYRQ1 uniquely delivers targeted HS signal conditioning without altering USB protocol behavior, enabling compliance recovery in space-constrained automotive and docking applications where passive switches lack gain and hub ICs add unnecessary complexity.

FAQ
What is the primary function of the TUSB213QRGYRQ1 in a USB 2.0 system?
The TUSB213QRGYRQ1 functions as a dedicated USB 2.0 High-Speed signal conditioner that compensates for inter-symbol interference (ISI) loss in transmission channels. It applies programmable AC and DC boost to restore eye diagram integrity at the USB connector without affecting Low Speed or Full Speed signaling - making it ideal for passing USB-IF electrical compliance tests in automotive and docking applications.
Does the TUSB213QRGYRQ1 require firmware or I²C configuration to operate?
No - the TUSB213QRGYRQ1 supports both pin-strapped and I²C configuration modes. In pin-strapped mode, AC boost is set via the EQ pin pulldown resistor and DC boost via the DC_BOOST pin strap; these values are latched at reset and require no firmware. I²C (address 0x2C) is optional for dynamic reconfiguration or status readback in advanced systems.
Can the TUSB213QRGYRQ1 be used in both host-side and device-side USB implementations?
Yes - the TUSB213QRGYRQ1 is host/device agnostic. Its D1P/D1M and D2P/D2M ports are functionally interchangeable; the device automatically detects LS/FS/HS mode and applies conditioning only to HS traffic regardless of orientation. This allows flexible placement between SoC and connector or between hub and cable in either direction.
What is the role of the VREG pin on the TUSB213QRGYRQ1?
The VREG pin on the TUSB213QRGYRQ1 is a 1.8-V LDO output that powers the internal core during High-Speed operation only. It requires a 0.1-µF bypass capacitor to GND for stability and is disabled in LS/FS/suspend modes - eliminating the need for an external 1.8-V supply and reducing system BOM count.
How does the TUSB213QRGYRQ1 handle USB On-The-Go (OTG) and Battery Charging (BC) protocols?
The TUSB213QRGYRQ1 is fully compatible with USB OTG 2.0 and BC 1.2 specifications because its signal conditioning is transparent to LS/FS signaling and protocol handshakes. It does not interfere with ID pin detection, D+ pull-up timing, or charging signature identification - ensuring seamless operation in dual-role and fast-charging applications.
