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)…
