Product details
Overview
TUSB213QRGYTQ1 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, provides programmable AC and DC boost (4 AC levels, 3 DC levels), operates from 4.4 V to 5.5 V, and delivers 30 mA typical active current at 480 Mbps - enabling reliable USB HS compliance in infotainment head units with long PCB traces or cable extensions.
For engineers reviewing the TUSB213QRGYTQ1 datasheet, TUSB213QRGYTQ1 pinout, TUSB213QRGYTQ1 application, or TUSB213QRGYTQ1 equivalent, key selection considerations include its AEC-Q100 Grade 2 qualification (–40°C to 105°C), host/device-agnostic D1P/D1M and D2P/D2M port interchangeability, ultra-low 0.76 mA HS suspend current, and I²C-configurable operation (address 0x2C) for dynamic tuning of signal integrity parameters.
Technical Context
The TUSB213QRGYTQ1 implements a patent-pending signal conditioning architecture that preserves LS and FS signal characteristics while applying adaptive equalization exclusively to HS differential pairs. Its dual-path design allows flexible placement - near the connector to pass USB near-end eye mask or near the PHY to improve far-end integrity.
Configuration is supported via pin-strapping (EQ for AC boost, DC_BOOST for DC gain) or I²C interface, with latched settings sampled on RSTN de-assertion. The device outputs status flags (CD for connection detection, ENA_HS for HS mode assertion) and supplies a regulated 1.8-V VREG output for internal core logic when active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.4 V to 5.5 V - compatible with standard USB VBUS without external regulation |
| Operating Temperature | –40°C to 105°C ambient - meets AEC-Q100 Grade 2 for automotive cabin environments |

Use Value: Maintains HS link reliability over full temperature range and vibration conditions without firmware intervention. | Use Scenario: Automotive-grade USB extension cable requires embedded signal regeneration to meet OEM HS timing budgets over 5 m length. IC Role / Device Role / Timing Role: TUSB213QRGYTQ1 integrated into cable assembly's inline module to boost both AC and DC components of HS signal. Use Value: Eliminates need for costly retimers or custom ASICs while achieving AEC-Q100-compliant performance. |
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 |
|---|---|---|---|
| TS3USB221AIPWR | Passive 2-channel USB 2.0 switch with 6 Ω on-resistance; no signal conditioning or boost capability | Used for USB port multiplexing, not signal restoration; lacks HS equalization, DC/AC boost, or automotive qualification | Select only when channel switching-not signal integrity enhancement-is required |
| MAX3353EETA+ | USB 2.0 transceiver with integrated ESD protection (±15 kV HBM); no equalization, boost, or AEC-Q100 rating | Designed for basic physical layer interface with robust ESD tolerance; no compensation for ISI or cable loss | Choose for cost-sensitive non-automotive designs where signal loss is negligible and ESD is primary concern |
Compared with TS3USB221AIPWR and MAX3353EETA+, the TUSB213QRGYTQ1 uniquely delivers programmable AC/DC boost, AEC-Q100 qualification, and USB-IF HS compliance support - making it the only viable option for automotive or long-channel USB 2.0 signal restoration where passive switches or basic transceivers fail to meet eye mask requirements.

FAQ
What is the primary function of the TUSB213QRGYTQ1 in a USB 2.0 system?
The TUSB213QRGYTQ1 functions as a High-Speed signal conditioner that compensates for inter-symbol interference (ISI) and channel loss in USB 2.0 links. It applies programmable AC and DC boost to restore differential eye opening without altering LS/FS signals. This enables reliable USB-IF electrical compliance testing at the connector - especially critical in automotive infotainment systems with long PCB traces or extended cables. The TUSB213QRGYTQ1 does not act as a switch, transceiver, or hub controller.
How does the TUSB213QRGYTQ1 handle Low Speed and Full Speed USB traffic?
The TUSB213QRGYTQ1 is explicitly designed to be transparent to Low Speed (1.5 Mbps) and Full Speed (12 Mbps) USB signaling. Its patent-pending architecture bypasses LS/FS signals without modification, preserving their voltage levels, timing, and waveform integrity. Only High Speed (480 Mbps) differential pairs undergo equalization. This ensures full backward compatibility with legacy USB devices while delivering targeted signal restoration where needed - a key requirement validated in the TUSB213QRGYTQ1 datasheet Section 7.1.
Can the TUSB213QRGYTQ1 be configured after power-up without resetting the device?
No. Configuration changes to AC boost (via EQ pin) or DC boost (via DC_BOOST pin) require toggling the RSTN pin to re-latch settings. The TUSB213QRGYTQ1 samples these pins only upon de-assertion of RSTN and ignores real-time adjustments thereafter. For dynamic tuning without hardware reset, the I²C interface (address 0x2C) must be used to write to registers ACB_LVL (0x01) and DCB_LVL (0x0E), followed by clearing CFG_ACTIVE (0x03) to restart the state machine - as specified in the TUSB213QRGYTQ1 register map.
What is the role of the VREG pin on the TUSB213QRGYTQ1?
The VREG pin on the TUSB213QRGYTQ1 is a 1.8-V LDO output that powers the internal digital core logic exclusively during High Speed mode operation. It is not active in LS/FS modes or shutdown. A mandatory 0.1-µF ceramic capacitor must be placed between VREG and GND to stabilize this output. This pin is not intended for external circuitry power; using it as such may compromise TUSB213QRGYTQ1 functionality or violate absolute maximum ratings.
Is the TUSB213QRGYTQ1 compatible with USB On-The-Go (OTG) and Battery Charging (BC) protocols?
Yes. The TUSB213QRGYTQ1 is explicitly qualified for compatibility with USB On-The-Go (OTG) 2.0 and Battery Charging (BC) 1.2 specifications, as stated in its official features list and Section 3 of the datasheet. Its host/device-agnostic D1P/D1M and D2P/D2M port configuration supports bidirectional OTG negotiation, while its transparent LS/FS path ensures BC detection logic (e.g., D+ pull-up recognition) remains unaltered - enabling correct charger identification and current negotiation in automotive and portable applications using the TUSB213QRGYTQ1.
