The IEEE802.3cg specification targets industrial, smart buildings, and automotive for 10 Mbit/s Ethernet networking. This includes two new physical standards: 10BASE-T1L and 10BASE-T1S. 10BASE-T1L addresses long reach point-to-point Ethernet networking across single pair Ethernet cable up to a minimum of 1,000 meters. 10BASE-T1S addresses short reach Ethernet networking across single pair Ethernet cable up to a minimum of 15 meters point-to-point (full-duplex), or 25 meters multi-drop (half-duplex). onsemi’s solution targets 10BASE-T1S multi-drop, half-duplex. 10BASE-T1S multi-drop means daisy chaining a minimum of eight Ethernet nodes or stations up to a minimum of 25 meters of single pair Ethernet cable. A multi-drop topology requires bus arbitration in order to prevent packet collisions. Packet collisions dramatically degrade the overall performance of the network. The IEEE 802.3cg specification introduces the physical layer collision avoidance (PLCA ) methodology as a means of preventing collisions. PLCA supersedes carrier sense multiple access collision detection (CSMA-CD).
