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.
