Texas Instruments TUSB6020ZQER

Overview

TUSB6020ZQER from Texas Instruments is an evaluation module (EVM) built around the TUSB6020 USB 2.0 high-speed On-The-Go (OTG) dual-role controller IC with integrated PHY, designed for seamless VLYNQ interface connectivity to TI DSP platforms including TMS320C6437 and DM6437. It supports full-speed (12 Mb/s), high-speed (480 Mb/s), and low-speed (1.5 Mb/s) USB operation, features a USB Mini-AB connector, dual clock sources (19.2 MHz oscillator or 24 MHz crystal), and configurable GPIO-based mode selection.

For engineers reviewing the TUSB6020ZQER datasheet, TUSB6020ZQER pinout, TUSB6020ZQER application, or TUSB6020ZQER equivalent, this EVM enables rapid validation of USB OTG host/device functionality, mass storage emulation, and VLYNQ-to-USB bridge integration in embedded DSP systems - with on-board reset control, power measurement jumpers, and mini-PCI edge connector compatibility.

Technical Context

The TUSB6020ZQER implements a complete hardware evaluation platform for the TUSB6020 IC, interfacing directly via a 128-pin mini-PCI edge connector to TI's DaVinci and C6000 DSP evaluation modules. Its VLYNQ bus interface operates at up to 100 MHz with matched trace routing and CRUN/CLK signaling, while the integrated USB PHY supports all USB 2.0 speeds and OTG session request protocol (SRP) and host negotiation protocol (HNP).

Power architecture includes dedicated LDOs: TPS77618 (1.8 V), TPS70848 (1.5 V / 3.3 V), and TPS2051B (VBUS switch), with test jumpers (J37–J59) enabling rail-by-rail current measurement. Configuration is managed through an 8-bit DIP switch (S1) tied to GPIO0–GPIO7, where GPIO7 must be pulled low for initialization and GPIO6 selects the clock source.

FAQ

What is the primary function of the TUSB6020ZQER?

The TUSB6020ZQER is an evaluation module designed to demonstrate and validate the TUSB6020 USB 2.0 On-The-Go dual-role controller IC. It enables engineers to implement USB host, device, or OTG functionality in TI DSP systems via VLYNQ interface - supporting use cases like USB mass storage emulation, peripheral attachment, and embedded host control. The TUSB6020ZQER itself is not a standalone IC but a fully assembled, tested board with supporting power, clock, and configuration circuitry.

Which DSP platforms is the TUSB6020ZQER compatible with?

The TUSB6020ZQER is explicitly validated for use with TI's TMS320C6437 and TMS320C6424 DSP evaluation modules, as well as the DM6437 Digital Video Development Platform. Compatibility relies on the presence of an active VLYNQ interface and a 128-pin mini-PCI slot - both required for mechanical and electrical connection. The EVM's schematic and layout are optimized for signal integrity on VLYNQ TX/RX lines and USB differential pairs (DP/DM).

Does the TUSB6020ZQER support USB high-speed (480 Mb/s) operation?

Yes, the TUSB6020ZQER supports full USB 2.0 compliance, including high-speed (480 Mb/s), full-speed (12 Mb/s), and low-speed (1.5 Mb/s) modes. This capability is enabled by the underlying TUSB6020 IC's integrated PHY and is verified in the SLAU242 User's Guide. Layout practices - such as 90 Ω differential routing for DP/DM, ground plane shielding, and controlled trace lengths - ensure signal integrity at 480 Mb/s on the TUSB6020ZQER board.

How is clock selection configured on the TUSB6020ZQER?

Clock selection on the TUSB6020ZQER is controlled by GPIO6 at power-up: when GPIO6 is pulled low (via Switch 7 OFF), the 24 MHz crystal (X2) is selected; when pulled high (Switch 7 ON), the 19.2 MHz oscillator (X1) is used. This setting is latched during initialization and determines the TUSB6020 IC's reference clock. The EVM includes design notes specifying placement proximity of X1/X2 and load capacitors (C2/C3) to U1 to minimize jitter and ensure stable USB timing.

Can the TUSB6020ZQER be used for production-level USB functionality?

No - the TUSB6020ZQER is designated strictly for engineering development, demonstration, and evaluation purposes per TI's Important Notice. It lacks certifications (FCC, CE, RoHS, WEEE), safety isolation, EMI filtering, and environmental hardening required for end-product deployment. However, its schematics, layout, power architecture, and component selection serve as a production-ready reference for integrating the TUSB6020 IC into custom PCBs targeting DSP-based USB applications.
