Analog Devices Inc. ADIN1111 10BASE-T1L Ethernet MAC-PHY Transceivers
Analog Devices ADIN1111 10BASE-T1L Ethernet MAC-PHY Transceivers are designed for industrial Ethernet applications and are compliant with the IEEE® 802.3cg-2019™ Ethernet standard for long-range, 10Mbps single-pair Ethernet (SPE). The ultra-low-power, single-port 10BASE-T1L transceivers feature an integrated media access control (MAC) interface, facilitating direct connectivity with various host controllers through a serial peripheral interface (SPI). The SPI allows lower-power processors without an integrated MAC, providing the lowest overall system-level power consumption.
The ADI ADIN1111 is developed for edge node sensors and field instruments deployed in building, factory, and process automation. The devices function from a single power supply rail of 1.8V or 3.3V, supporting both 1.0V and 2.4V. The internal hybrid and termination resistors enable the ADIN1111 to connect directly to the MDI interface.
The ADIN1111 has incorporated voltage supply monitoring and power-on reset (POR) circuitry to enhance system-level robustness and has a 4-wire SPI for communication between the MAC interface and the host processor.
The ADIN1111 is housed in a 32-lead, 5mm x 5mm lead frame chip scale package (LFCSP).
