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.
