STMicroelectronics STEVAL-OET005VD

Overview

STEVAL-OET005VD from STMicroelectronics is a USB Type-C evaluation kit comprising the STEVAL-OET005D evaluation board and STEVAL-OET005E testing board, designed to validate ESD protection and common-mode filtering solutions for data (SSTx/SSRx), control (CC1/CC2/SBU), and power (VBUS) lines using 0201- and 500 µm-pitch discrete devices including ECMF4-40A100N10, ECMF02-2HSMX6, and ESD051-1BF4.

For engineers reviewing the STEVAL-OET005VD datasheet, STEVAL-OET005VD pinout, STEVAL-OET005VD application, or STEVAL-OET005VD equivalent, this kit enables hands-on validation of USB 3.2-compliant transient suppression, differential signal integrity preservation, and dual-role port (DRP) protection architecture under real-world VBUS stress conditions up to 20 V.

Technical Context

The STEVAL-OET005VD implements a layered protection strategy: ECMF4-40A100N10 provides integrated common-mode choke + ESD protection for high-speed differential pairs (SSTx/SSRx), while ECMF02-2HSMX6 handles D+/D− lines with 100 MHz common-mode rejection; ESD051-1BF4 devices protect CC, SBU, and sideband use (SBU) pins with 5.1 V clamping and 8 kV IEC 61000-4-2 contact discharge rating.

Board-level design supports flexible VBUS configuration via solder bridges (5 V / 9 V / 15 V / 20 V), isolates shield from ground plane to prevent ground loop coupling, and maintains flow-through routing for Dp/Dn and SSTx/SSRx paths to preserve impedance control and minimize stub-induced reflections.

FAQ

What is the difference between STEVAL-OET005VD and STEVAL-OET005VC?

The STEVAL-OET005VD uses ECMF4-40A100N10 and ECMF02-2HSMX6 for combined common-mode filtering and ESD protection on high-speed and legacy USB lines, respectively, and integrates ESD051-1BF4 for CC/SBU protection in 0201 package. STEVAL-OET005VC relies on HSP051-4M10 and HSP061-2M6 in 500 µm pitch without integrated filtering - making STEVAL-OET005VD better suited for USB 3.2 Gen 2 noise-sensitive designs.

Can STEVAL-OET005VD be used to test USB Power Delivery (USB-PD) sink behavior?

Yes - the board supports VBUS configurations up to 20 V via solder bridges and includes dedicated CC1/CC2 protection circuitry compatible with USB-PD communication. However, it does not include a PD controller (e.g., TCPP02); users must connect an external PD controller or source to evaluate sink-side protection and fault response under PDO negotiation.

Which USB 3.2 signal integrity parameters are preserved by the STEVAL-OET005VD layout?

The STEVAL-OET005VD maintains controlled 90 Ω differential impedance on SSTx/SSRx traces, uses flow-through routing with minimal stubs (<0.5 mm), and places ESD devices directly at connector pads - enabling accurate measurement of insertion loss, return loss, and TDR step response up to 10 GHz, as verified in ST's DB4670 Rev 3 characterization.

Is shield connection to ground supported on the STEVAL-OET005VD board?

No - the USB Type-C connector shield is intentionally left floating and not connected to the PCB ground plane, per ST's design intent to avoid ground loop coupling and enable isolation testing. Users requiring shield grounding must add external 0 Ω resistors or capacitors between shield pads and system ground during integration.
