3 Description

Designed for harsh industrial environments, the

DP83822 is an ultra-robust, low-power single-port

10/100 Mbps Ethernet PHY. The DP83822 provides

all physical layer functions needed to transmit

and receive data over 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. The device supports multiple industrial fieldbuses

with fast link-down detection as well as Auto-MDIX in

forced modes.

The DP83822 offers an remarkable 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 TLK105, TLK106,

TLK105L and TLK106L 10/100 Mbps Ethernet PHYs.

The DP83822 comes in a 32-pin 5.00-mm × 5.00-mm

VQFN package.
