For example, in April 2025, Infineon Technologies AG entered into an agreement to acquire Marvell Technology’s Automotive Ethernet business for US$2.5 billion in cash. This acquisition aims to strengthen Infineon’s existing microcontroller portfolio and support its development of system solutions for software-defined vehicles. The transaction is still subject to regulatory approval. Ethernet, known for its low-latency and high-bandwidth communication, is crucial for software-defined vehicle architectures and could also have applications in related areas like robotics. The acquisition is expected to bolster Infineon’s R&D presence in the United States.

Segments that transform the industry

Based on Data Rate, the market is bifurcated into 10-100 Mbps, 100-1000 Mbps, and Greater than 1 Gbps. Among these, the Greater than 1 Gbps segment is leading the market. The driver behind the expansion of the global Ethernet PHY chips with a speed of greater than 1 Gbps can be explained by the advancement of 5G, cloud services, video sharing, online gaming, and enterprise networking, all of which require internet at higher speeds. High-speed and reliable data transmission is highly required by industries and consumers of communication equipment; thus, there is a need to incorporate an Ethernet PHY chip set that would enable data speeds of more than 1 Gbps. Hence, it is suitable in applications such as telecommunication, the automobile industry, and business networking that demand low latency and high bandwidth for the best end-user experience.
