Ethernet Technology

Ethernet is a key enabling technology for low-latency, high-bandwidth communication. It quickly and reliably transfers large amounts of data between components such as microcontrollers, processors and sensors. This makes it crucial for software-defined vehicles. Additionally, it has significant potential in adjacent fields of use such as humanoid robots.

“We’re incredibly proud of what our team has achieved in building a world-class Automotive Ethernet business,” says Matt Murphy, chairman and CEO of Marvell. “Infineon is the right company to take this business to the next level – with the scale, portfolio breadth, and customer reach to unlock its full potential. We’re confident this move will create exciting opportunities for continued growth, and we look forward to seeing the team thrive as part of Infineon.”

The business’ design-win pipeline of around $4 billion by 2030 and strong innovation roadmap offers significant potential for future revenue growth. In the calendar year 2025, the business is expected to generate revenue of US$225 – US$250 million with a gross margin of around 60 percent. The purchase price amounted to US$2.5 billion.
