Overview
The ADIN2111BCPZ, produced by Analog Devices Inc., is a low-power, 2-port 10BASE-T1L transceiver designed specifically for industrial Ethernet applications. It is compliant with the IEEE 802.3cg-2019 Ethernet standard for long reach, 10 Mbps single pair Ethernet (SPE). This device integrates a media access control (MAC) and a switch, enabling direct connectivity with various controllers via a serial peripheral interface (SPI). The ADIN2111 supports various network topologies, including line, daisy-chain, and ring configurations, and can operate in unmanaged modes where it automatically forwards traffic between the two Ethernet ports.
