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.
