Data Sheet
FEATURES
GENERAL DESCRIPTION
10BASE-Te/100BASE-TX IEEE® 802.3TM compliant
MII, RMII and RGMII MAC interfaces
100BASE-TX RGMII latency transmit: <124 ns, receive <250 ns
100BASE-TX MII latency transmit: <52 ns, receive <248 ns
EMC test standards
The ADIN1200 is a low power, single-port, 10 Mbps and 100 Mbps
Ethernet transceiver with low latency specifications designed
for industrial Ethernet applications.
This design integrates an energy efficient Ethernet (EEE) physical
layer device (PHY) core with all associated common analog
circuitry, input and output clock buffering, management
interface and subsystem registers, and media access control
(MAC) interface and control logic to manage the reset, clock
control and pin configuration.
IEC 61000-4-5 surge ( 4 kV)
IEC 61000-4-4 electrical fast transient (EFT) ( 4 kV)
IEC 61000-4-6 conducted immunity (10 V)
EN55032 radiated emissions (Class A)
EN55032 conducted emissions (Class A)
Unmanaged configuration using multilevel pin strapping
EEE in accordance with IEEE 802.3az
Start of packet detection for IEEE 1588 time stamp support
Enhanced link detection
The ADIN1200 is available in a 5 mm × 5 mm, 32-lead lead
frame chip scale package (LFCSP) and can operate with a single
3.3 V supply, assuming the use of a 3.3 V MAC interface supply.
For maximum flexibility in system level design, a separate VDDIO
supply enables the management data input/output (MDIO) and
MAC interface supply voltages to be configured independently
of the other circuitry on the ADIN1200 allowing operation at
1.8 V, 2.5 V, or 3.3 V. At power-up, the ADIN1200 is held in
hardware reset until each of the supplies has crossed its minimum

rising threshold value and the power is considered good. Brownout
protection is provided by monitoring the supplies to detect if
one or more of them drops below a minimum falling threshold
and holding the device in hardware reset until the power supplies
return and satisfy the power-on-reset (POR) circuit.

operation
Low power consumption
139 mW for 100BASE-TX
3.3 V/2.5 V/1.8 V MAC interface VDDIO supply
Single-supply operation with 3.3 V VDDIO
Integrated power supply monitoring and POR
The MII management interface (also referred to as MDIO
interface) provides a 2-wire serial interface between a host
processor or MAC and the ADIN1200, allowing access to
control and status information in the PHY core management
registers. The interface is compatible with both IEEE® 802.3™
Standard Clause 22 and Clause 45 management frame
structures.
APPLICATIONS
Industrial automation
Process control
Factory automation
Robotics and motion control
Building automation
The ADIN1200 can support cable lengths up to 180 meters.
Test and measurement
Industrial internet of things (IoT)
Note that throughout this data sheet, multifunction pins, such
as XTAL_I/CLK_IN/REF_CLK, are referred to either by the
entire pin name or by a single function of the pin, for example,
XTAL_I, when only that function is relevant.
