以太网控制器-DP838348CVV数据手册

　　The DP83848I 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. In addition to low power，

　　the DP83848I is optimized for cable length performance far exceeding IEEE specifications.

　　The DP83848I 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 DP83848I easily interfaces to twisted pair media

　　via an external transformer and fully supports JTAG

　　IEEE specification 1149.1 for ease of manufacturing.

　　Additionally both MII and RMII are supported ensuring

　　ease and flexibility of design.

　　The DP83848I 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.

　　The DP83848I is offered in a small form factor （48 pin

　　LQFP） so that a minimum of board space is needed.
