Product Overview
Texas Instruments DP83822I is a single-port 10/100 Mbps Ethernet physical layer transceiver for Signal_Chain designs using copper or fiber Ethernet links. The PHY supports 100BASE-TX and 10BASE-Te copper operation, and it can support 100BASE-FX when connected to an external fiber optic transceiver.
For host connection, DP83822I provides RGMII, RMII, and MII MAC interface options. System clocking can use a 25 MHz or 50 MHz source, and the device supports 3.3 V, 2.5 V, and 1.8 V I/O voltage options. Power figures from the extracted data list analog supply power below 120 mW with the 1.8 V AVD single-supply option and below 220 mW with the 3.3 V AVD single-supply option.
The device is supplied in a 32-pin VQFN package with a 5.00 mm x 5.00 mm nominal body and operates across -40°C to 125°C. It includes Energy Efficient Ethernet, Wake-on-LAN with magic packet detection, programmable energy savings modes, IEEE 1588 start-of-frame detect support, cable diagnostics, built-in self-test, loopback capability, rapid link-down detection, and Auto-MDIX support in forced modes.
