Texas Instruments DP83822 10/100 Ethernet PHY Transceiver
Texas Instruments DP83822 10/100 Ethernet Physical Layer (PHY) Transceiver 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. 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 fast link-down timing as well as Auto-MDIX in forced modes. The Texas Instruments DP83822 offers an 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 TLK105, TLK106, TLK105L, and TLK106L 10/100 Mbps Ethernet PHYs.Features
