General Description

The DP83848M PHYTER Mini addresses the quality, reli-

ability and small form factor required for space sensitive

applications in embedded systems.

The device offers performance far exceeding the IEEE

specifications, with superior interoperability and industry

leading performance beyond 137m of Cat-V cable. The

DP83848M also offers Auto-MDIX to remove cabling com-

plications. DP83848M has superior ESD protection,

greater than 4KV Human Body Model, providing extremely

high reliability and robust operation, ensuring a high level

performance in all applications.

National’s DP83848M incorporates a number of system

cost-reducing features not found on other supplier’s Physi-

cal layer products. For example, the DP83848M incorpo-

rates a 25MHz clock out that eliminates the need and

hence the space and cost, of an additional Media Access

Control (MAC) clock source component. In addition, both

MII and RMII are supported ensuring ease and flexibility of

design.

The DP83848M 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

• Base stations
