13  The ADIN1110 is a low power single port 10BASE-T1L MAC-
14  PHY designed for industrial Ethernet applications. It integrates
15  an Ethernet PHY core with a MAC and all the associated analog
16  circuitry, input and output clock buffering.
17
18  The ADIN2111 is a low power, low complexity, two-Ethernet ports
19  switch with integrated 10BASE-T1L PHYs and one serial peripheral
20  interface (SPI) port. The device is designed for industrial Ethernet
21  applications using low power constrained nodes and is compliant
22  with the IEEE 802.3cg-2019 Ethernet standard for long reach
23  10 Mbps single pair Ethernet (SPE).
24
25  The device has a 4-wire SPI interface for communication
26  between the MAC and host processor.
