Here are some key considerations for cabling and topology:

‍

◾ Cable Type: Use twisted pair cables specified for 10BASE-T1S for optimal performance.

‍

◾ Cable Length: Limit the total segment length to 25 meters, including stubs and they should not exceed 10 cm each.

‍

◾ Bus Topology: Employ a multidrop configuration (daisy chain) to connect nodes. Each node taps into this bus at its respective connection point.

‍

◾ Node Spacing: Maintain a minimum 1-meter distance between nodes for reliable signal transmission. Distribute nodes evenly along the bus to avoid signal reflections and ensure balanced loading.

‍

◾ Bus Termination: Proper termination with 100-ohm resistors is essential.By following these guidelines, you can ensure a robust and efficient 10BASE-T1S network.

‍

Here are key bullet points for implementing 10Base-T1S by a development team:

‍

◾ Adhere to IEEE 802.3cg Standard: Implement the 10BASE-T1S PHY and MAC layers according to the IEEE 802.3cg-2019 specification.

‍

◾ Use Differential Manchester Encoding (DME): Employ DME modulation with 4B5B encoding for robust clock recovery, low DC baseline wander, and improved EMC performance in noisy automotive environments

‍

◾Implement PLCA with Round Robin Scheduling: Ensure the PLCA protocol grants transmit opportunities to nodes in a round robin sequence, enabling orderly, collision-free communication on the multidrop bus.

‍

◾Incorporate ESD Protection and Clock Requirements: Include ESD elements per transceiver application notes, positioned near connectors or common mode chokes, and ensure clock sources meet ±100 ppm tolerance including aging and temperature effects

‍

◾Validate with Comprehensive Testing: Conduct all transceiver and system tests in a consistent configuration per specifications, document layouts and configurations, and validate driver and transceiver implementations focusing on buffer handling, error scenarios, and timing compliance for multidrop scenarios
