Product Details

The ADIN2111 is a low power, 2-port 10BASE-T1L transceiver designed for industrial Ethernet applications, and is compliant with the IEEE® 802.3cg-2019 Ethernet standard for long reach, 10 Mbps single pair Ethernet (SPE). Featuring an integrated media access control (MAC) and a switch, the ADIN2111 enables direct connectivity with a variety of controllers via a serial peripheral interface (SPI). The switch (cut through or store and forward) supports various routing configurations between the two Ethernet ports and the SPI host port providing a flexible solution for line, daisy-chain, or ring network topologies.

The ADIN2111 can be used in unmanaged configurations where the device automatically forwards the traffic between the two Ethernet ports.

The device integrates the switch, two Ethernet physical layer (PHY) cores with a MAC interface and all the associated analog circuitry, and input and output clock buffering. The device also includes internal buffer queues, the SPI and subsystem registers, as well as the control logic to manage the reset and clock control and hardware pin configuration.

The ADIN2111 has an integrated voltage supply monitoring circuit and power-on reset (POR) circuitry to improve system level robustness. The 4-wire SPI for communication with the host can be configured to OPEN Alliance SPI or generic SPI. Both modes support optional data protection or cyclic redundancy check (CRC).
