General Description

The DP83848K addresses the quality, reliability and small

form factor required for space sensitive applications in

embedded systems operating in the industrial temperature

range.

The DP83848K offers performance far exceeding the

IEEE specifications, with superior interoperability and

industry leading performance beyond 137m of Cat-V

cable. The DP83848K also offers Auto-MDIX to remove

cabling complications. DP83848K has superior ESD pro-

tection, greater than 4KV Human Body Model, providing

extremely high reliability and robust operation, ensuring a

high level performance in all applications.

DP83848K offers two flexible LED indicators - one for Link

and the other for Speed. In addition, both MII and RMII are

supported ensuring ease and flexibility of design.

The DP83848K is offered in a tiny 6mm x 6mm LLP 40-pin

package and is ideal for industrial controls, building/factory

automation, transportation, test equipment and wireless

base stations.

Applications

• Peripheral devices

• Mobile devices

• Factory and building automation
