ADIN1111 Single-Pair Ethernet MAC-PHY for 10BASE-T1L Applications The ADIN1111 from Analog Devices is a highly integrated MAC-PHY device designed for 10BASE-T1L Ethernet communication over single twisted-pair cabling. It enables long-reach Ethernet connectivity (up to 1 km) in industrial and building automation environments, where traditional Ethernet cabling is impractical or cost-prohibitive.

This device supports SPI and MII interfaces, allowing seamless integration with MCUs and FPGAs. It includes diagnostic features, low power operation, and robust EMC performance, making it suitable for deployment in harsh environments. The ADIN1111 is ideal for retrofitting legacy 4 mA to 20 mA and HART systems with Ethernet connectivity, enabling Industry 4.0 and IIoT applications.

Supports up to 1 km reach over a single twisted pair (unshielded or shielded)
Dual host interface: SPI (up to 25 MHz) and MII

Integrated link diagnostics and cable health monitoring
Low power consumption with flexible power management modes

Applications

Industrial automation and process control
Building automation and HVAC systems
Condition monitoring and predictive maintenance

Retrofitting legacy analog sensor networks
Remote I/O and edge node connectivity in IIoT systems
