DP83822HRHBT Description

Ideal for harsh industrial environments, the DP83822HRHBT is an ultra-robust, low-power single-port 10/100 Mbps Ethernet PHY. It 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 DP83822HRHBT provides flexibility to connect to a MAC through a standard MII, RMII, or RGMII interface. The DP83822HRHBT offers integrated cable diagnostic tools, built-in self-test, and loopback capabilities for ease of use. It supports multiple industrial field buses with its fast link-down detection as well as Auto-MDIX in forced modes.
