CISPR 25 qualified automotive EMC lab launched by Marvell

1 min read

Marvell Technology Group has announced the opening of its automotive electromagnetic compatibility (EMC) lab.

The EMC testing facility is CISPR 25 qualified and provides Marvell with an in-house capability to perform a range of emission, immunity and ESD testing.

With its lab, Marvell’s automotive Ethernet products can now be designed into system solutions, which it believes will help meet the demanding EMC challenges faced by automotive manufacturers shorten the time-to-market.

To deliver improved levels of user experience, safety and security, automotive makers are employing several electronic control units (ECUs) that operate at higher frequencies, which pose new EMC challenges. These ECUs are more frequently being bombarded by multiple sources of electromagnetic interference (EMI) and noise, ranging from 150KHz to over 10GHz from both internal ECUs and external sources. Preventing these electromagnetic interferences, enables the mission critical functions of the car to operate reliably. Furthermore, limiting the electromagnetic interference in the car ensures that the infotainment systems including streamed audio and video run seamlessly and without interruption.

The coexistence of an increasing number of ECUs within the car, as well as interference from surrounding vehicles have driven automotive silicon vendors to meet very stringent EMC and ESD requirements outlined in the IEC/ISO and AEC-Q100 standards. Marvell says its EMC lab provides the testing capability needed to ensure its products and solutions meet these EMC requirements, including IEC CISPR 25, IEC 62132, IEC61967, IEC 61000, ISO11452, ISO 10605, ISO7637 and other OEM specific EMC requirements.

“The automotive mega trends of vehicle electrification, assisted and autonomous driving and the advanced connectivity solutions create an increasingly challenging EMC and ESD environment that have to be solved," said Ian Riches, director, Global Automotive Practice, Strategy Analytics.

"Automotive silicon vendors are now being asked to develop capabilities and shoulder more of the responsibility in developing practical recommendations that overcome these challenges.

“The opening of the Marvell EMC lab is an important milestone for the automotive industry and will provide Marvell with an edge with this unique facility.”
