description: |
The ADIN1110 is a low power single port 10BASE-T1L MAC-
PHY designed for industrial Ethernet applications. It integrates
an Ethernet PHY core with a MAC and all the associated analog
circuitry, input and output clock buffering.
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 device has a 4-wire SPI interface for communication
between the MAC and host processor.
