onsemi T30HM1TS2500 Automotive Ethernet Transceiver
onsemi T30HM1TS2500 Automotive Ethernet Transceiver is IEEE 802.3cg compliant and integrated with a media access controller (MACPHY). This transceiver is a next-generation 10BASE-T1S device capable of communicating with multiple nodes connected to a shared medium at 10Mbps. Collisions at the physical layer are prevented due to the physical layer collision avoidance (PLCA) with CSMA/CD MAC and PHY, improving the throughput of CSMA/CD. onsemi T30HM1TS2500 Automotive Ethernet Transceiver is suitable for both automotive and industrial applications.
