3 Description

The DP83822 is a low power single-port 10/100 Mbps Ethernet PHY. It provides all physical layer functions needed to transmit and receive data over both standard twisted pair cables or connect to an external fiber optic transceiver. Additionally, the DP83822 provides flexibility to connect to a MAC through a standard MII, RMII or RGMII interface.

The DP83822 offers integrated cable diagnostic tools, built-in self-test and loopback capabilities for ease of use. It supports multiple industrial buses with its low deterministic transmit and receive latency as well as fast link-down timing.

The DP83822 offers and innovative and robust approach for reducing power consumption through EEE, WoL and other programmable energy savings modes. 

The DP83822 is a feature rich and pin-to-pin upgradeable option for the TLK105L and TLK106L 10/100 Mbps Ethernet PHYs.

The DP83822 comes in a QFN 32-pin 5.00-mm ×5.00-mm package.
