DP83848CVV

TEXAS INSTRUMENTS  DP83848CVV  以太网控制器, 100 Mbps, IEEE 802.3u, 3 V, 3.6 V, LQFP, 48 引脚

The DP83848C is a robust fully featured 10/100 single port Physical Layer device offering low power consumption, including several intelligent power down states. These low power modes increase overall product reliability due to decreased power dissipation. Supporting multiple intelligent power modes allows the application to use the absolute minimum amount of power needed for operation. The DP83848C includes a 25MHz clock out. This means that the application can be designed with a minimum of external parts, which in turn results in the lowest possible total cost of the solution. The DP83848C easily interfaces to twisted pair media via an external transformer. Both MII and RMII are supported ensuring ease and flexibility of design. The DP83848C features integrated sublayers to support both 10BASE-T and 100BASE-TX Ethernet protocols, which ensures compatibility and interoperability with all other standards based Ethernet solutions.
