ADIN2111 2-Port Ethernet Switch

ADI's ADIN2111 adds Ethernet connectivity to every node in a building using long reach 10BASE-T1L technology, harmonizing the building network with Ethernet to simplify network management. ADIN2111 supports low power edge node designs and interfaces to a wide variety of host controllers via SPI. Coming complete with a suite of diagnostic features, it enables real time fault detection and fault location identification with 2% accuracy over 1 km of cables, reducing system downtime and commissioning time. It enables networks of sensors, actuators, controllers, and fire panels to be connected in a line and ring topology while utilizing existing deployed single, twisted pair cabling infrastructure.

The EVAL-ADIN2111EBZ is a flexible platform enabling quick evaluation of the ADIN2111 robust, low power 10BASE-T1L 2-port Ethernet switch. The evaluation board provides two 10BASE-T1L channels with 10 Mbit per second single pair Ethernet (SPE) connections reaching up to 1.7 km of link distance. The ADIN2111 internal switch can be configured in store and forward mode between the two 10BASE-T1L channels and the SPI host. Cut through mode is also available between port 1 and port 2 and can be used without the need of the SPI host (unmanaged configuration).
