Vehicle Network Technology Advancements
A startup specializing in Ethernet-based vehicle network technology is leveraging a 7nm fabrication process to produce advanced chips aimed at meeting the high bandwidth demands of software-defined vehicles (SDVs). These vehicles require significantly more data bandwidth due to features such as advanced driver assistance systems (ADAS), autonomous driving, and over-the-air software updates.
Ethernet-Based Transceivers
The startup has developed Ethernet-based transceivers, designated ENT11100 and ENT11025, capable of supporting multiple data rates (10 Gbps, 5 Gbps, 2.5 Gbps, and 1 Gbps) within the same device. These transceivers are expected to help Original Equipment Manufacturers (OEMs) address the increasing data demands while simplifying thermal design.
- ENT11100: Supports IEEE 802.3ch multi-gigabit (10/5/2.5GBASE-T1) and IEEE 802.3bp (1000BASE-T1).
- ENT11025: Supports IEEE 802.3ch multi-gigabit (2.5GBASE-T1) and IEEE 802.3bp (1000BASE-T1), and is software and pin compatible with the ENT1x100, allowing for a seamless migration path with a single PCB design.
Advanced Fabrication Process
Ethernovia, the company behind these transceivers, utilizes a 7nm process for manufacturing, which offers several advantages:
- Power Optimization: Enhanced power efficiency due to advanced process technology.
- High Integration Levels: Supports higher levels of integration, resulting in a low power, high port density solution.
Industry Support and Future Developments
Andreas Aal from Volkswagen Group highlighted the importance of fast, secure data transmission for electrification, connectivity, and automated driving functions. Ethernovia’s new PHY devices meet these needs by offering energy-efficient, high-bandwidth, and low-latency data transmission with embedded co-optimized safety and security IP. This paves the way for a seamless transition to future software-defined vehicle architectures.
These transceivers are part of Ethernovia’s planned family of products, which will include a high-bandwidth, low-latency switch being developed in partnership with Continental, a leading OEM. The single-port ENT11100 and ENT11025 are currently open for customers, with quad-port devices expected to be introduced later this year.
Conclusion
Ethernovia’s advanced 7nm Ethernet-based transceivers are set to play a crucial role in the evolution of software-defined vehicles, providing the necessary bandwidth and performance to support the growing demands of modern automotive technology.
