Product Details

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.
