13 The ADIN1110 is a low power single port 10BA
14 PHY designed for industrial Ethernet applica
15 an Ethernet PHY core with a MAC and all the
16 circuitry, input and output clock buffering.
17
18 The ADIN2111 is a low power, low complexity,
19 switch with integrated 10BASE-T1L PHYs and o
20 interface (SPI) port. The device is designed
21 applications using low power constrained nod
22 with the IEEE 802.3cg-2019 Ethernet standard
23 10 Mbps single pair Ethernet (SPE).
24
25 The device has a 4-wire SPI interface for co
26 between the MAC and host processor.
