STMicroelectronics STEVAL-OET002V1

Overview

STEVAL-OET002V1 from STMicroelectronics is a medium-dependent interface (MDI) evaluation board designed to validate EMI filtering and ESD protection performance of the EMIF02-01OABRY filter in BroadR-Reach™ automotive Ethernet applications. It supports differential signal integrity up to 100 Mbps, operates from -40 °C to +125 °C, complies with ISO10605 and ISO7637-3, and features four RF SMA connectors for VNA characterization and transceiver-to-harness interface testing.

For engineers reviewing the STEVAL-OET002V1 datasheet, STEVAL-OET002V1 pinout, STEVAL-OET002V1 application, or STEVAL-OET002V1 equivalent, this board enables direct validation of BroadR-Reach™ MDI compliance-including Sdd21 attenuation profile, common-mode noise suppression, differential impedance matching (100 Ω ±10%), and transient robustness under coupled ESD stress on UTP lines.

Technical Context

The STEVAL-OET002V1 implements a two-port passive filter network centered on the EMIF02-01OABRY dual-channel EMI/ESD solution, configured to preserve differential signaling integrity while attenuating common-mode noise above 30 MHz. Its layout maintains controlled 100 Ω differential impedance across J1–J2 (transceiver side) and J3–J4 (harness side), with no ground connection required on the UTP side.

It supports full BroadR-Reach™ EMC test conditions per the BroadR-Reach Transceiver EMC Test Specification, including 8 kV contact ESD per ISO10605 applied directly to MDI pins, and burst immunity per ISO7637-3. The board does not include active circuitry or power regulation-only passive filtering and RF interconnects.

FAQ

What is the primary purpose of the STEVAL-OET002V1 board?

The STEVAL-OET002V1 is a dedicated evaluation platform for verifying the EMI filtering and ESD robustness of the EMIF02-01OABRY device in BroadR-Reach™ automotive Ethernet channels. It enables S-parameter measurement, differential impedance verification, and standardized EMC stress testing without modifying transceiver hardware.

Does STEVAL-OET002V1 require external power or firmware?

No. The board is fully passive and contains no active components, power regulators, or microcontrollers. It operates without power supply, firmware, or configuration-functioning solely as a calibrated interconnect between transceiver and UTP harness for signal integrity and EMC validation.

Can STEVAL-OET002V1 be used with BroadR-Reach™ transceivers other than ST's?

Yes. Its SMA-based interface and 100 Ω differential routing are protocol-agnostic. Engineers have successfully used it with Broadcom BCM8981x, Marvell 88Q1010, and NXP TJA110x transceivers to validate MDI-level EMC performance per BroadR-Reach™ specification.

How is ESD testing performed using this board?

ESD is applied directly to the MDI pins (J3/J4) per ISO10605:2001, using 8 kV contact discharge while monitoring transceiver output eye diagrams and error rates. The board's layout ensures transient energy is shunted through the EMIF02-01OABRY's integrated TVS diodes, protecting downstream silicon.
