Analog Devices Inc. ADIN1110 Low Power 10BASE-T1L Ethernet MAC-PHY

Analog Devices Inc. ADIN1110 Low Power 10BASE-T1L Ethernet MAC-PHY integrates an Ethernet PHY core with a MAC and all the associated analog circuitry, input and output clock buffering. The ADIN1110 features a single power supply rail of 1.8V or 3.3V and is designed for industrial Ethernet applications.

The Analog Devices ADIN1110 Low Power 10BASE-T1L Ethernet MAC-PHY provides programmable transmit levels, external termination resistors, and independent Rx/Tx pins, enabling the device for intrinsic safety applications. The ADIN1110 has integrated voltage supply monitoring and power-on reset circuitry to improve system-level robustness.

The Ethernet MAC-PHY offers a 4-wire SPI interface for communication between the MAC and host processor. The ADIN1110 is housed in a 6mm x 6mm 40-lead package.
