Product details 

       The ADIN1100 is a low power single port 10BASE-T1L transceiver designed for industrial Ethernet applications and is compliant with the IEEE 802.3cg Ethernet standard for long reach 10 Mb/s Single Pair Ethernet. It integrates an Ethernet PHY core with all the associated analog circuitry, input and output clock buffering, the management interface control register and subsystem registers, as well as the MAC interface and control logic to manage the reset and clock control and pin configuration.

       The PHY core supports the 1.0 V pk-pk operating mode and the 2.4 V pk-pk operating mode defined in the standard and can operate from a single power supply rail of 1.8V or 3.3V, with the lower voltage option supporting the 1.0 V pk-pk transmit voltage level.

       The 1.0 V pk-pk operating mode, external termination resistors and independent Rx/Tx pins make the ADIN1100 suited to intrinsic safety applications.

       The ADIN1100 has an integrated voltage supply monitoring circuit and power on reset circuitry to improve system level robustness.

       The MDIO interface is a two-wire serial interface for communication between a host processor or MAC and the ADIN1100, thereby allowing access to control and status information in the PHY core management registers. This interface is compatible with IEEE 802.3 Std Clause 45 management frame structures. The MDIO interfaces of microcontrollers that only support IEEE 802.3 Std Clause 22 cannot be used in their default manner with the ADIN1100 MDIO interface. A common alternative is to use two GPIO pins to replicate the IEEE 802.3 Std Clause 45 frame in software.

       The ADIN1100 is available in a 6 mm × 6 mm 40-ld package.
