New single-pair Ethernet (SPE), or 10BASE-T1L, physical-layer standards developed by the IEEE are offering novel connectivity solutions for communicating asset health insights for condition-based monitoring (CbM) applications. SPE provides a shared power and high bandwidth data architecture, where 10-Mb/s data and power are shared on a low cost two-wire cable at over 1,000-meter distances.
Analog Devices designed the industry’s first 10BASE-T1L MAC-PHY (ADIN1110), which is a SPE transceiver with embedded MAC. The ADIN1110 communicates with an embedded microcontroller using a simple SPI bus, reducing both power consumption and firmware development time for the sensor.
