+description: |
+ The 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
+
+ Specifications about the charger can be found at:
