Switching with TSN capabilities, like Automotive gPTP, can increase the complexity of development and testing processes but may solve the challenges of your use cases. We can help you with simple easy-to-use switch configurations for complex development and test scenarios.
In the realm of zonal-based architectures, the unifying thread that ties everything together is the Ethernet network. Within this framework, all data seamlessly transforms into Ethernet frames, readily accessible by all domain controllers along the network backbone. This connectivity is made possible thanks to the widespread adoption of Ethernet-based networks and components.
In addition to high-speed Automotive Ethernet (T1), Ethernet 10BASE-T1S is a low-cost, low-speed, multidrop version of Automotive Ethernet widely considered for the replacement of CAN and CAN FD. Its material costs are approaching that of CAN, but it also eliminates the need for gateways by natively supporting Ethernet protocols such as TCP/IP, UDP, and gPTP.

Choosing the right Automotive Ethernet switch is crucial for reliable and efficient in-vehicle communication. We understand you're looking for the best balance of reliability, flexibility, price, performance, and ease of use. What are your top priorities? Let us know your specific challenges so we can help you find the ideal solution.
When selecting an Automotive Ethernet switch, consider these essential features:
Opt for a switch with an easy-to-use configuration tool (e.g., web server or remote configuration messages) for simple setup and management, avoiding the need for complex NDA-bound chip vendor configurations.
At minimum, single VLAN support is essential for network segmentation, improving performance and security. Double VLAN support provides even greater flexibility.
Look for features like port mirroring and segmentation for effective monitoring and control of traffic on specific ports.
Wake-up/sleep functionality is crucial for minimizing power consumption in automotive applications.
Support for network time synchronization standards like AVNU gPTP (802.1AS) and PTPv2 ensures synchronized devices, essential for many automotive applications.
Dual-speed capability (100BASE-T1 and 1000BASE-T1) ensures compatibility with a wide range of Automotive Ethernet devices.
Features like bandwidth reservation and ingress rate limiting help prioritize critical traffic and prevent network congestion.
Advanced data filtering tables enable granular traffic filtering based on various criteria (MAC address, IP address, TCP/UDP port number), enhancing security and performance
Jumbo frame support improves performance for high-bandwidth applications.
For demanding real-time applications like ADAS and autonomous driving, TSN support (including 802.1Qav, Qci, Qbv, and Qbu) is essential for deterministic and low-latency communication.
10BASE-T1S offers a compelling solution for cost-sensitive automotive applications, providing a low-speed, multidrop Ethernet option. Choosing the right 10BASE-T1S networking device is crucial for successful implementation. Here are key features to consider:
Determine the necessary communication protocol support for your application. Will you need to bridge to CAN, LIN, or other protocols?
Ensure the device supports the required 10 Mbps data rate of 10BASE-T1S. Consider future needs and whether the device also supports higher speeds like 10/100/1000BASE-T1 and BASE-TX.
Verify support for multidrop functionality, enabling multiple devices to share a single cable, reducing cabling complexity and cost.
Confirm adherence to the IEEE 802.3cg standard for 10BASE-T1S to ensure interoperability and reliable performance.
Prioritize devices with low power consumption to minimize energy usage, especially important in automotive environments.
Select devices designed for harsh automotive conditions, considering operating temperature range, vibration, and shock resistance.
Based on our experience, we recommend the following 10BASE-T1S devices.
