SNLS638A December 2018 – August 2019 DP83825I
The DP83825I is a fully-featured single-port Physical Layer transceiver compliant to IEEE802.3 10BASE-Te and 100BASE-TX standards. The device supports the standard Reduced Media Independent Interface (RMII) for direct connection to Media Access Controller (MAC).
The device is designed for a single 3.3-V power supply with an integrated LDO to provide voltage rails needed for internal blocks. The device allows I/O voltage interfaces for 3.3 V or 1.8 V. Automatic supply configuration within the DP83825I allows for any combination of VDDIO supply and AVDD supply without the need for additional configuration settings.
The DP83825I uses mixed-signal processing to perform equalization, data recovery, and error correction to achieve robust operation over a CAT5e twisted-pair cable greater than 150 meters. DP83825I supports various Low Power features like Active Sleep, IEEE Power Down and Deep Power Down. It also supports Energy Efficient Ethernet and Wake-on-LAN.
