　　The ADIN1300 is a low power, single port, Gigabit Ethernet transceiver with low latency and power consumption specifications primarily 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 MAC interface and control logic to manage the reset and clock control and pin configuration.

　　The ADIN1300 is available in a 6 mm × 6 mm, 40-lead lead frame chip scale package (LFCSP). The device operates with a minimum of 2 power supplies, 0.9 V and 3.3 V, 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 ADIN1300, allowing operation at 1.8 V, 2.5 V, or 3.3 V. At power-up, the ADIN1300 is held in hardware reset until each of the supplies has crossed its minimum rising threshold value. Brown-out protection is provided by monitoring the supplies to detect if one or more supply drops below a minimum falling threshold (see Table 17), 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 (also known as management station (STA)) and the ADIN1300, allowing access to control and status information in the PHY core management registers. The interface is compatible with both the IEEE 802.3 Standard Clause 22 and Clause 45 management frame structures.

　　The ADIN1300 can support cable lengths up to 150 meters at Gigabit speeds and 180 meters when operating at 100 Mbps or 10 Mbps.

　　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/CLK_IN, when only that function is relevant.

　　Evaluating the ADIN1300 Robust, Industrial, Low Latency, and Low Power 10 Mbps, 100 Mbps, and 1 Gbps Ethernet PHY

　　The EVAL-ADIN1300FMCZ allows simplified evaluation of the key features of the ADIN1300 robust, industrial, low latency gigabit, 10 Mbps, 100 Mbps, and 1 Gbps, Ethernet physical layer (PHY). The EVAL-ADIN1300FMCZ is powered by a single, external, 5 V supply rail that can be supplied either via the EXT_5V connector or via the P4 plug. All chip supplies are regulated from the 5 V rail providing supply rails required for AVDD3P3, VDD0P, and VDDIO. The P3 field programmable gate array (FPGA) mezzanine connector (FMC) connector is provided for connection to a master FPGA system for the media access control (MAC) interface and management data input/output (MDIO) control. The P5 connector provides an alternative means for MDIO control. The EVAL-ADIN1300FMCZ is fitted with a 25 MHz crystal (Y1). For complete specifications for the ADIN1300 device, see the ADIN1300 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-ADIN1300FMCZ.
