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.
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.
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.
The ADIN1200 can support cable lengths up to 180 meters.
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.
