DP83822, 10/100 Ethernet Physical Layer Transceivers

Texas Instruments offers its DP83822, robust, low-power, 10/100 Ethernet physical layer transceivers

Image of Texas Instruments' DP83822 10/100 Ethernet Physical Layer TransceiversTexas Instruments' DP83822 is a low-power, single-port, 10/100 Mbps Ethernet PHY. It provides all of the physical layer functions needed to transmit and receive data over standard, twisted-pair cables or to 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 as well as 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 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. It comes in a QFN, 32-pin, 5 mm x 5 mm package.
