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.
