Aeonsemi, a leader in high-speed Ethernet ICs, is entering the automotive market with the introduction of Nemo, a complete IEEE 802.3ch-compliant multi-gigabit Ethernet chipset for In-Vehicle Networking (IVN) applications. Nemo features the first automotive switch with integrated 10GBASE-T1 PHYs and the industry’s lowest power 10GBASE-T1 PHYs for symmetric and asymmetric communications.
Providing end-to-end solutions, the chipset comprises a CSI-2 serializer bridge, a CSI-2 deserializer hub, a single/dual-port PHY, and a 6-port zonal switch.
Ethernet has emerged as the technology of choice in automotive networking. It enables zonal Electrical/Electronic (E/E) architecture leading to significant performance improvements, wiring harness weight reduction and cost savings. However, high-speed sensor links have remained separate from the Ethernet IVN.
They rely on proprietary point-to-point SerDes technology due to the lack of high-speed, low-power, cost-effective asymmetrical Ethernet solutions. The Nemo chipset bridges this gap by offering the industry’s lowest power 10G/5G/2.5G symmetric and asymmetric connectivity in Energy Efficient Ethernet (EEE) mode over 15 meters of single-twisted-pair or coaxial cable. The AS30110 serializer consumes less than 300mW with a 10Gbps payload and less than 200mW with a 5Gbps payload. The AS30010/20 single/dual-port PHYs consume under 800mW power per port in symmetric 10Gbps mode.
“With the increased adoption of Advanced Driver Assistance Systems (ADAS) and Full Self-Driving (FSD), the market for sensors, including cameras, radar, and LiDAR, is expected to grow at a 14% Compound Annual Growth Rate (CAGR) to $27 billion by 2028.”, says Pierrick Boulay, Senior Technology & Market Analyst, Automotive Semiconductors at Yole Group
Ethernet-based sensors can significantly reduce automotive sensing system cost as more sensors are added to each vehicle.
