TEXAS INSTRUMENTS DP83822IRHBT Ethernet Physical Layer Transceiver, 3.15 V to 3.45 V, VQFN-32

The DP83822IRHBT is a robust, low power 10/100Mbps Ethernet physical layer transceiver in 32 pin VQFN package. It provides all physical layer functions needed to transmit and receive data over both standard twisted-pair cables or connect to an external fibre optic transceiver. Additionally it provides flexibility to connect to a MAC through a standard MII, RMII or RGMII interface. It offers integrated cable diagnostic tools, built-in self-test and loopback capabilities for ease of use. It supports multiple industrial buses with its fast link-down timing as well as Auto-MDIX in forced modes. It is a feature rich and pin-to-pin upgradeable option for the TLK105, TLK106, TLK105L and TLK106L 10/100Mbps Ethernet PHYs. It is used in motor and motion control, IP network cameras.
