1.3 Description
The DP83848x device addresses the quality, reliability and small form factor required for space sensitive
applications in embedded systems.
The DP83848x offers performance far exceeding the IEEE specifications, with superior interoperability and
industry leading performance beyond 137 meters of Cat-V cable. The DP83848x also offers Auto-MDIX to
remove cabling complications. DP83848x has superior ESD protection, greater than 4 kV Human Body
Model, providing extremely high reliability and robust operation, ensuring a high-level performance in all
applications.
DP83848J/K 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 DP83848H/M/T incorporates a 25-MHz clock out that eliminates the need and hence the space and
cost, of an additional clock source component.
The DP83848x is offered in small 6-mm × 6-mm WQFN 40-pin package and is ideal for industrial controls,
building/factory automation, transportation, test equipment and wire-less base stations.
