GENERAL DESCRIPTION

The ADIN1101 is a low power, single port, 10BASE-T1L transceiver

designed for industrial Ethernet applications and is compliant with

the IEEE® 802.3cg-2019™ Ethernet standard for long reach 10

Mbps single pair Ethernet (SPE). The ADIN1101 integrates an

Ethernet physical layer (PHY) core with all the associated analog

circuitry, input and output clock buffering, the management interface

control register and subsystem registers, as well as the MAC

interface and control logic to manage the reset, clock control, and

pin configuration.

The ADIN1101 supports cable reach of up to 1700 meters with

autonegotiation enabled and has ultra low power consumption of 39

mW.

The PHY core supports 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, with the

lower voltage option supporting the 1.0 V p-p transmit voltage level.

The ADIN1101 has an integrated voltage supply monitoring circuit

and power-on reset (POR) circuitry to improve system level robustness.

The MDIO interface is a 2-wire serial interface for communication

between a host processor or MAC and the ADIN1101, thereby

allowing access to control and status information in the PHY core

management registers. This interface is compatible with both the

IEEE 802.3 Standard Clause 22 and Clause 45 management frame

structures.
