GENERAL DESCRIPTION The ADIN2111 is a low power, low complexity, two-Ethernet ports switch with integrated 10BASE-T1L PHYs and one serial peripheral interface (SPI) port. The device is designed for industrial Ethernet applications using low power constrained nodes and is compliant with the IEEE® 802.3cg-2019™ Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE). 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 supports cable reach of up to 1700 meters with ultra low power consumption of 77 mW. The two PHY cores support the 1.0 V p-p operating mode and the 2.4 V p-p operating mode defined in the IEEE 802.3cg standard, and can operate from a single power supply rail of 1.8 V or 3.3 V. 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 media access control (MAC) interface and all the asso- ciated 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 robust- ness. 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). Analog Devices is in the process of updating documentation to provide terminology and language that is culturally appropriate. This is a process with a wide scope and will be phased in as quickly as possible. Thank you for your patience. |
