DP83822IRHBR

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.
