Analog Devices Introduces Complete Long-Range Ethernet Solution for Digitalization of Building Automation Networks Embedded Designs

     Analog Devices, Inc. (ADI) introduces a complete 10BASE-T1L Ethernet solution for building automation networks. With the help of networked digital automation equipment, total building management from heating, ventilation and air conditioning to living comfort can be achieved. The new product, ADIN2111, adds long-distance Ethernet connectivity to controllers, sensors and actuators, enabling more efficient and sustainable building management. The ADIN2111 is ideal for use in small, power-constrained edge devices, saving up to 50% in power consumption and up to 75% in PCB space compared to discrete solutions.

     The ADIN2111 reduces retrofit costs by daisy-chaining data across wire and ring networks using a single twisted pair cabling infrastructure already deployed in the building. The ADIN2111 features enhanced diagnostic capabilities that utilize the real-time information provided on link quality and fault location to resolve problems efficiently and quickly, reducing commissioning, installation, and system downtime. Compliant with the IEEE 802.3cg standard, the solution enables Ethernet connectivity over cable lengths up to 1.7km, supports ring redundancy and soft real-time protocols such as Modbus/TCP, BACnet/IP and KNX.

Main features of ADIN2111:

● Ultra-low power consumption: 80mW

● Small package: 7mm x 7mm LFCSP

● SPI host interface, no need for microcontroller with integrated MAC interface

● Advanced packet filtering through 16 MAC address lookup tables, reducing the burden of prioritizing traffic management on the processor

● Support IEEE 1588 timestamp
