  "textContent": "We’ve reported on 10BASE-T1S and 10BASE-T1L Single Pair Ethernet (SPE) chips from Microchip and Analog Devices in the past, which support Ethernet communication over a single twisted-pair cable. But those chips integrate a full Ethernet PHY or MAC-PHY inside the device. NXP takes a different approach with their TJA1410 (automotive) and TJF1410 (industrial) Physical Medium Dependent (PMD) transceivers. These new PMDs separate the analog physical layer from the digital Ethernet logic. By integrating the digital portion of the PHY into the host microcontroller or switch, the TJA1410 and TJF1410 only need to handle the essential analog functions for transmitting and receiving signals over the physical medium. They communicate with the host via a 3-pin OPEN Alliance (OA) interface. TJA1410 and TJF1410 PMD transceivers specifications: Networking – 10BASE-T1S (Compliant with IEEE 802.3cg and OPEN Alliance TC14,TC10 specifications) Host Interface – 3-pin OA interface (requires host MCU/switch with a 10BASE-T1S digital PHY) [...]\n\nThe post NXP TJA1410 and TJF1410 PMD transceivers enable “CAN-like” Single Pair Ethernet (SPE) connectivity appeared first on CNX Software - Embedded Systems News.",
